Since I couldn't edit my first post, here is another question. When I went to edit the admin/customers.php file, it said that the new code should go "about line 1173". There are only 1135 lines total. Where should I add the new code?

This is my second zen cart so I'm not a total newbie but these pathes could use just a bit more explanation, or is there a more appropriate section where I should be looking? I've tried faq's and searches...

Thanks!
Casey
