New Post: Attached document files in product list

Hi my NB friends
I have this question, I need to download the attached file directly in product list.

on product list template I insert

<div class="Document"><div class="DocumentDescription">[TAG:DOCDESC1]</div>[TAG:DOC1:<prop CssClass="DocumentIcon" />][TAG:DOCLINK1:<prop CssClass="DocumentLink" text="Download" />]</div>

But the link don't work, error 500, I imagine because there isn't the product ID, can you help me to add the parameter for obtain a functional link.

if for example in the query string I add /ProdID/46 the detailed template appear and the file download

thanks
Fabio
