I'll be brief, if you don't mind. It was recommended I use Foxycart as a solution so I have been trying to set it up. The behavior is not at all what I would expect. I have since made a basic, very basic site, to isolate what may be wrong. It too has the exact same behavior.
You can see what I mean at: mitchellmillron.com where the 'add to cart' brings up the overlay too low, and, well, you have to see to understand.
I have tried both the form and link method for products with the same result. I added what was recommended by the docs. I don't know what else to try.
One thing that I cannot seem to find is the class 'foxycart' on any of the included stylesheets. I was trying to trace the class but since I can't find 'foxycart' I've gotten a little frustrated.
So, anyone who feels like telling me what lame error I have made, feel free :-) Cause I'm really at my wit's end here!
