Allowing user to edit Total

[twins]

HI I am running the paypal version ( I modified some stuff to make it workm on my server since I have an asp account ( cheaper ) and cannot run other scripts. I would like users to be able to edit the total without having complex coupons etc.

For instance If in my live chat I agree with a user on a 10$ discount then the user puts -10 in a box and recalculates total. Is there any simple mod in which I can do this. THanks

Create a form under the managecart, like a product, use text input for price, but price will be a negative number!

There you go.....

got it how stupid of me..i will put it in the checkout though thanks.
A more interesting option is the simple coupon mod that I found recently on this forum..thanks.
