If I put my Paypal button on my ASP.net website, it doesn’t work because the whole page is wrapped in a <form runat="server"></form> tag.
What’s the best way to integrate:
<form action="https://www.paypal.com/cgi-bin/webscr" method="post">
....
</form>
Onto my ASP.net page?
You need to use the PayPal NVP API. Gives you much more flexibility than the pre-made buttons as well.
