Bill,
Do not ask how this happened, but when I traced down the bug with the tag name rather than the content of the Product listing box, it turns out that in catalog/includes/modules/sts_inc/sts_column_left.php
Line 31 $sts->restart_capture ('category_cssmenu', 'box');
needed to be changed to
Line 31 $sts->restart_capture ('categorycssmenu', 'box');
so that it tied up with the rest of the template. Works fine now. I'll stress again, I uploaded the template right from the package without editing any files. Anyone else seen this?
Thanks again for your help in clarifying what the variable name should have been. keep up the good work!
Pat
