OK, I have been working on this for quite a while and am not getting very far. I have just installed credit class v5.03 and am having trouble getting the modules to appear under Admin->Modules->Order Total. Nothing shows up when I put ot_coupon.php and ot_gv.php in the catalog/includes/modules/order_total directory. If I remove them the rest of the modules show up. As soon as I put them back in, everything disappears.
Any Help would be greatly appreciated.
