I'm looking to setup a product with variable pricing based the user selection of a custom field radio box or input into a custom field text box. I'm trying to accomplish a "donation" product with 5 suggested donations (radio boxes) and a spot for "other amounts" for the user to enter a custom donation value (see attached sample form). I'd like the value from the radio box or text field to be passed into the price when taken to the checkout / payment screen. Any ideas / help on how to make this happen? Thanks in advance! Question 2: Is it possible to create a custom signup form without any payment options? I just want to collect Name, Email and Phone and create a new amember account with that info. It would be even better if this basic signup form could be posted as an HTML form on any page on the website - not just the signup.php page.
