Just wanted to add a comment about this mod. The version found here:
http://www.oscommerce.com/community/contributions,1373
DOES work with OSC 2.2 MS2. I have personally installed version "20 Jul 2003 - Categories Description MS2 1.5" on OSC 2.2 MS2, and it works great. Thank you for the update to the original version 1.1 which was not compatible with OSC 2.2 MS2, this is a great contrib!!!
The only thing I should mention is that within the installation instructions, step #4 for changes for "catalog/index.php", it mentions looking for the line "// We build the manufacturers Dropdown ...". This line is not in the code, however if you go down to around line 258, you should fine the line it mentions,
"?> <td width="100%" valign="top"><table border="0" width="100%" cellspacing="0" cellpadding="0"> " . This is where you need to be for step # 4.
Other than that, the instructions are accurate.
Hope this helps a little bit, for those having trouble getting this contrib to work on OSC 2.2 MS2.
