shopping cart

[jamie61880]

          Hi everyone. I have this one page on our site that we would like for customers to order some parts from. It is separate from our current database on our site and there really are no part numbers because the calculations for the parts are on the fly (depending what the user chooses). Here's the link: https://www.ironwoodelectronics.com/elastomer.cfm We do not have our certificate updated yet, so you might get the unsecured page, but it's safe to use. We're not going to ask for credit card info. on here. I think we're going to go through stripe.com for that.

          But what I don't know how to do is to create a shopping cart for this page. If the user goes through and chooses the correct dimensions of what he needs, I have the info. with pricing output to a table at the bottom. The problem is if they choose a different part with different dimensions, I lose the info. from the first option. This is why I need to do a shopping cart. I want each option they choose, to display in the table and then if they want to clear one, they can. I would also probably need the Quantity field to be in the table also. I have a different table created for each of the 4 part options in the drop down because that was the only way I could get it to work correctly. Here's the code I have for this page below. Thanks for your help.

For a start, isDefined('page.select_Part') is always False. You have defined the variable, page.select_Part, nowhere.

[jamie61880]

How do you define the variable? I set it to form.PartNumber. The code works the way it is. I just don't understand how to create a shopping cart. I tried to put the items in the drop down into an If Statement, so I wouldn't need so much repetitive code, but this was the only way I could make it work.
