I have follow the instrutions to build a Paypal Form but when I get to paypal it says Error- Empty Page... can you let me know what is happening please. This is the form... http://app.formassembly.com/forms/view/10641
For the record (this has been answered by email already), the PayPal connector only accepts numerical values in the quantity and unit price fields. The issue was caused by a unit price of '$25.00'. Changing it to '25.00' fixed the problem. We'll try to improve the input validation to prevent further errors.
