Categories almost ends - unresolved error

Receiving an unspecified error when returning from the view to the list on line 94 of listview:

print '@lt;a href="herbsview.php?id=' . dbOut($row['HerbID']) . '&cid=' . $myID . '&cat=' . $_GET['cat'] . '">';

This is a line I added while adding categories.

Times up for now. I'll have to leave it this way until I can sit back down to it.

time spent on categories so far: 3 and a half hours.
