I'm trying to test a paypal form through the sandbox, and have created a preconfigured test account.
However, when I go through my paypal form and enter the password I am proceeded with this error:
"The link you have used to enter the PayPal system is invalid. Please review the link and try again."
I am unsure what this error means. I removed my email address I am aware it shows as xxxxxxxx@gmail.com in the example below.
My form is below:
<form name "_xclick" action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post">
SteamID: <input type="text" name="item_number" value="<?php echo $steamid;?>" size="45">
