Problem: Your club is sponsoring an event, and you need to collect the money and headcount.
Solution: A form that joins the contact fields, some basic arithmetic and error checking, and a running total for user convenience.
- T-Shirts: More than 4 option fields
Sep/2008 Upgrade: PayPal changed things so you are no longer limited to only on0/os0, on1/os1 option vars.
I've tested up to on9/os9 and go through just fine!!

Problem: PayPal tells you how to pass 2 values; if you know how, you can pass 4 ... but you really need to pass 5.
Solution: join the fields and send up.

Following is a modified version of what PP_Frank posted in the Code Samples Library:
“There are times when you have a form and you want to have an email sent to you with that information and also send the customer to PayPal for payment with one button.
This example will show you how to do that. There are two parts to this. ”
