2 Tax Modification

[AlphaandOmega]

Randy,

I have used your two tax system for my website. But there has been a problem. Even with the original nopcart.js from the website you posted the output doesnt work. The taxes work put the id and product name wont come up in the email. Tried another configuration etc. i am using an asp checkout but i think the problem lies within the the nopcart. I would really aprreciate some advise. The website is http://www.demoland.nl

I took a peek at your site...everything in the checkout function looks OK to me.

Before you do anything else, edit checkout.htm line 106:

<FORM
onsubmit="if(CheckForm(this)){SetCookie ('NumberOrdered', 0, null, '/'); return true;} else { return false; }"

to read:

<FORM
onSubmit="return CheckForm(this)"

you may be passing an empty cart to checkout.asp.

Then, it that isn't the problem, read on...

To find out if the info is being passed along properly, add this in place of the blank line at 818:

alert(strOutput);

This will display an alert box with all the items ordered in it when you call up the CheckoutCart function...you should get the item's info in the order it is given in lines 809 to 814...

OutputItemId + strFooter should be the item's order number followed by the item count...1, 2, 3 etc.

If everything is there as it should be, go to the checkout.asp and make sure that page is expecting the same variable names with the info in them...I don't know what the ASP equivalent to an alert box is, but that would tell you if the info is being passed correctly.

Hi,

After implementing Randy's code, I got the following error on line 1194: 'ItemWeight' is undefined.

Did anyone run into this before? your assistance is appreciated.

At the beginning of nopcart.js where the tax rate is set, add the line

ItemWeight = 0;

By defining the variable at the start of nopcart.js you will not see that error again.

Hi,

That seemed to do the trick - thanks!

The next issue is the shipping. It seems to be fixed at 6.50 even though I set the shipping cost for the items through the form

Code: Select all

<input type=hidden name="SHIPPING" value="10.00">

I found the following through quick search through the nopcart.js :

Code: Select all

function ComputeShipping(Zone, NoQty, Wgt, TotVal, ship) {
Shipping = 6.50;
...


Can you give some examples on how to calculate shipping costs? I have various size items with various associated shipping costs.

Thanks again.

[Randy]

If you are setting the SHIPPING for each item this is the way to do it:

<input type=hidden name="SHIPPING" value="10.00">

If you buy one it costs $10 to ship it, while 3 of the same thing would be $30.

In the example you give, the shipping cost was set for a flat rate of $6.50 in the code you quoted:

Code: Select all

 
function ComputeShipping(Zone, NoQty, Wgt, TotVal, ship) {
Shipping = 6.50;
... 


Rather remove the line, change it to read:

Shipping += 0;

or whatever you want to charge as a minimum flat rate to be added to the SHIPPING amounts.

There are a number of methods for computing shipping...some offer shipping as a percentage of the total cost of the products, some discount it as the total goes up, or some offer flat rates in steps based on the total.
Then there is by distance, weight, and of course by SHIPPING value set on each item.

About the only way I haven't seen is by the phase of the moon, or by the day of the month (As in COP's speeding ticket quotas). The best way is to determine how you ship your products, (Mail, UPS, FedEx etc) and work up a cost table that can be translated into a formula, and code that into nopcart.js. You can even compute shipping by different methods, and have the customer select (and pay for) their preference.

Don't forget to add GST on Shipping...you have to pay it!

Hi Randy,

Thanks for the fast reply. The full function looks like this :

Code: Select all

//-----------------------------------------------------------------------||
// FUNCTION: ComputeShipping                                             ||
// PARAMETERS: Zone, Total Quantity, Weight, Total Value, preset amount  ||
// RETURNS:  Shipping Cost                                               ||
// PURPOSE: Compute shipping cost total Qty and shipping zone            ||
//-----------------------------------------------------------------------||
 
function ComputeShipping(Zone, NoQty, Wgt, TotVal, ship) {
Shipping = 6.50;
// LocationValue = GetCookie("ZoneSelected");

    // ------------------- Calculate shipping by total order weight ------------||

    // ------------------- fWeight is in lbs or Kilograms ----------------------||
    // - between this weight and    this ,  shipping costs this ----------------||
if ( Wgt >  0.00 && Wgt <=  0.50 ){ Shipping +=  3.30 };
if ( Wgt >  0.50 && Wgt <=  1.00 ){ Shipping +=  4.40 };
if ( Wgt >  1.00 && Wgt <=  2.00 ){ Shipping +=  5.50 };
if ( Wgt >  2.00 && Wgt <=  5.00 ){ Shipping +=  6.60 };
if ( Wgt >  5.00 && Wgt <= 10.00 ){ Shipping +=  7.70 };
if ( Wgt > 10.00 && Wgt <= 15.00 ){ Shipping +=  8.80 };
if ( Wgt > 15.00 && Wgt <= 20.00 ){ Shipping += 10.00 };
if ( Wgt > 20.00 && Wgt <= 25.00 ){ Shipping += 11.10 };
if ( Wgt > 25.00 && Wgt <= 30.00 ){ Shipping += 12.20 };
if ( Wgt > 30.00 ){ Shipping  += 15.50; }


/*
if (LocationValue != Zone) {
SetCookie("ZoneSelected", Zone, null, "/");
location.href=location.href;
   }
   
var ItemQty = parseInt(NoQty);
if (LocationValue == 0 ){
  var ship =  (ItemQty * 5.00);
  return (ship);
}
if (LocationValue == 1 ){
  var ship =  (ItemQty * 7.00);
  return (ship);
}

if (LocationValue == 99 ) return 0.00;
*/
   return Shipping;
}


if I change it to

Code: Select all

Shipping += 0;

I get Error: Object expected

Ultimately what I'm trying to achieve is the ability to charge for shipping on a per item basis, where the shipping price varies from one province to another. I am from Ontario, so shipping to Ontario will be X. Shipping to other provinces would be X + some fixed amount. The fixed amount will vary by province

[Randy]

I might have missed something...try changing the Shipping = 6.50; to Shipping = 0.00;

forget the += stuff.

As for computing shipping, take a look at the UPS shipping by zone mod. This could be modified to make it work for provinces if there is either a math relationship between the provinces shipping costs, or if a provincial flat rate would be enough to cover the differences.

Canada Post offers an online calculator based on the shipper and destination postal codes. I don't know if there is one to download.

Shipping = 0.00; causes the shipping total to be 0. It ignores the <input type=hidden name="SHIPPING" value="10.00"> defined in the item forms.

[WingNut]

any ideas how I can get this going?

[Randy]

I have isolated the problem and here is the fix:

In Nopcart.js

change line 857 to FShipping from fShip
so it reads:
fShipping += (parseInt(fields[1]) * parseFloat(fields[4]) );

delete line 913:
fShipping = ComputeShipping(LocationSelected, fItems, fWeight, fTotal, fShip);

and line 1172:

fShipping = ComputeShipping(LocationSelected, fItems, fWeight, fTotal, fShip);

That will fix it up!!

OK, that took care of the intermediate step of managing the shopping cart. To make the calculation easy, I made the product price $100, and the shipping $10. The cart showed correct totals until I hit the checkout button have a look at http://www.logicscape.com/pokerandgaming and tell me what you think...

Thanks.

[Randy]

I must have missed a couple!

Remove the following from lines 1172 and 1225 (and anywhere else you see them)

fShipping = ComputeShipping(LocationSelected, fItems, fWeight, fTotal, fShip);

It will work then!!

Also your checkout page is too wide...iI have to do a horz. scroll--managecart is OK.

Randy,

First off, great script...it has really helped me out in a jam. The question I have is:

is there anyway to have the GST and PST Calculated when the "Ontario" Radio button is seleted...when the radio button for "others" is checked off to have the GST = 0?

thanks
Jay

[Randy]

I have been playing with a 3rd radio button:

"Ontario" for GST + PST
"Other Canadians" for GST only
"Other Countries" no PST, no GST

You would then add the GST on shipping into the cost of shipping.

This is only necessary if you are using a Payment Processor, so an easier way to do it would be to show the Provincial Sales Tax as a separate row just like the GST, add both taxes together for the 3 radio buttons and the Payment Processor would get one tax figure.

This would probably work for the 2 Provinces that use the combined HST.
HST is easier to calculate--there is nothing tax exempt!

Let me know what you think.
