Have seen a couple of posts using events and custom formats on this but can't get them to work...settled on custom format which seems easiest:
$value = "<a href=".$value."><img src=\"images/pdf.gif\"></a>";
In List view GIF shows but file links doesn't work ... seems to be bec. linked files are saved in sub directory called docsin/
Any ideas on how to modify code (".$value.") value string to point to docsin/ sub directory much appreciated...
