HTML Form from, need help

[ebcus]

Hi:
I need some hlep in html/PHP coding.

I bought a PHP scripts from a company and the script suppose
to let people pick the products and pay by paypal from my website, once they pay, script should forward them to my signup page, problem is "the script doesn't forward people to my signup page after they paid by paypal". I check with that company and no answer for several days.

Method Not Allowed
The requested method POST is not allowed for the URL /affcgi/thanks.htm.

Some one suggest me to add a line of code inside the form,
I did add
<input type="hidden" name="return" value="http://www.example.com/affcgi/signup.htm">
to the form, and then I got error message when it try to forward
DOn't know why it had error when try to forward?

ERROR MESSAGE:
"Method Not Allowed
The requested method POST is not allowed for the URL /affcgi/signup.htm "
Any one know how to get rid of this error and forward my page to signup.htm from paypal page? Thanks.

My scripts are like this:

<form action="https://www.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_xclick">
...............................
...............................
<input type="hidden" name="return" value="http://www.example.com/affcgi/signup.htm">
.............................
</form>

YOu help or suggestion is highly appreciated.

My suggestion is very non-proffesional:
maybe making a .php return page would fix it? (instead of signup.htm make signup.php)

It's not thinking of the error itself, but trying to bypass it without understanding it. And I considered myself a future programmist/developer... SHAME ON ME FOR THIS ONE!
