I've created a form which works fine until I pass it across into PayPal. The form has different prices for different quantities so I set up a product dropdown menu for each price and the fixed quantities (20, 30, 40, etc.). There are 3 additional extras which can be added, I tried to do these as an option with 3 checkboxes but the total didn't work so I used 3 separate product fields with 'Yes/No' radio buttons for the extra to be added. Each one opened an hidden quantity field associated with it when clicked on 'Yes'. This obviously created lots of quantity fields in the admin but they worked OK until the form was submitted to PayPal which won't display the additional extra with it's associated quantity. Can anyone help me with this?
