I have a running site for a non-profit, and am using "_donation" cmd input field. (e.g, "<input type="hidden" name="cmd" value="_donations" />" I'd like to use the more secure s-xclick, but have an issue with it. First, some background. The organization runs a golf outing, and needs to charge depending upon how many people register for a team (1 to 4) at $150/person. By using "_donation", I can fill in the "amount" input field with a specific value, and all works well. For s-xclick, when I make the button, I must either specify a particular amount, or allow the user to enter the amount. In the first case, PayPal places that specific amount in the payment page. In the second case, no amount is entered in the payment page, instead prompting the user to enter the amount. Any attempt to enter an amount in the "amount" input field is ignored. So, neither of these scenarios is what I need. In total, then, I'd like the ability to make a secure button, but still be able to enter the amount to charge on an "amount" input field in my web page. Can this be done?
