001 accessed approved check click clickbank clicks code documentation ebook ejunkie error link mentions message page pay products sales site somebody thank-you

When somebody clicks an ebook on my site, they are taken to Clickbank to pay and for each ebook the thank you link on Clickbank is the ejunkie code
"http://www.e-junkie.com/ecom/cf.php". Is this right? I can't test it because when I click on it I get a message from CB " Error 001: This page will not work when accessed directly or via test sales". Therefore, how do I check this out?

Our documentation for ClickBank mentions (for this very reason) that we only work with ClickBank products which are already approved.
