This request is for Zen-Cart.
I sell prints online based on square footage. My customer must be able to select width and height (both in inches) of the desired print. The shopping cart dynamically calculates the total square footage and shows the total amount to be paid based on the square footage price I will set in admin. This total will obviously be the total only for the square footage. Options and shipping charges will be separate.
I forgot to mention, the calculation must be done without the whole page refreshing.
Coders are asking about my website. Well, I decided on Zen-Cart as shopping cart, but haven't installed it yet because I didn't know this customization was possible. It looks like it is possible.
So, I will go ahead and install Zen-Cart 1.3.8 and PM you the website.
After that you tell me what you need.
Sorry about my lack of clarity.
