Increasing the item in Cart when adding the same product

Postby foreigner » Tue Mar 09, 2010 8:27 pm

Hi all,

Somewhow my

if ( !bAlreadyInCart ) {
iNumberOrdered++;

script does not work. If I add the same item to the cart once again, the item adds itself as a new line to the cart
instead incresing its amount within the cart. I could not find out why.
Any help is appreciated.

Here is my AddToCart script:
Code: Select all

I'm having the exact same problem! Any help would be appreciated. Either increasing the quantity or throwin up an alert works for me. Just want one of them to work.

I got it to work finally. I went back and added field by field until it worked.
