Also the most common reason add-ons fail to work is from faulty installs. (this has NOTHING to do with experience or skill level.. a bad install can happen to anyone -- as evidenced by my own support question in this same thread not even a few weeks ago)

That said I just took a look at your site again and realized that your Template Monstrosity template is a possible source of your issues.. TM designers have a nasty habit of slashing out code the designer deems unnecessary in order to force their designs to look pretty.. (every last one of their designs does not require half the crap they do to achieve the design)

You might want to take a look t your template files (the original ones) and see if the good folks at Template Monstrosity have overwritten one of more of the checkout pages. If they have, in doing so they may have removed code COWOA needs to work correctly..
I agree with Diva, but if you really want to make sure install cowoa on zen cart Classic Contemporary Green default template to see if cowoa will work. This way you will know..... I bet it does.
