How to create custom formula for shopping list

Hi there -

Here is what I am trying to do. I have a business that allows people to shop with us I would like to create an application, that uses Zoho Creator, where users can click a check box and then get a report of the equivalent from our store.

So for example

If the form had a section called Bathroom supplies and there were a series of checkbox like like

Soap
Shampoo
Mouthwash
Shower Cleaner

When the user chose a few products and submitted the form it would show our product and price based on those checkboxes.

Acme Soap on a Rope $6.00
Acme Shampoo $4.00

I am very open to how to accomplish this. I could create a spreadsheet that has a formula that simply said "if cell is checked then value = "

Hope that makes sense.
