Here is a reply from Steve over at vb.com

That is the problem. The Replacement Variables do not replace the links to attachments. They replace specific text added to a post. So you cannot use Replacements to do what you want in this case.

In fact there is no function to do this. This requires modifying the code. We cannot officially support code modifications or forums running modified code, however you can try searching or asking for help with this over at http://www.vbulletin.org.

Back to the drawing board. Do you have any other suggestions
