Paypal post problem

document.aspnetForm.action = "https://www.paypal.com/cgi-bin/webscr";

I use master page and paypal payment page but giving error "document.as开发者_如何学JAVApnetform is not defined"

I can't tell from your question whether you are doing this on the client using JavaScript or on the server in C#. I guess the former as you are using document all lower case. Either way check your capitalisation - Javascript is case sensitive so you may need document.AspNetForm or something similar as your identifier. Just make sure it matches up to whatever the title of the form is in the source code.
