I'm running a Wordpress blog at http://www.simplye-books.com/blog/?pageid=14 and I installed the plugin so that Ejunkie will work with Wordpress....but it isn't. I put the code to "Add to Cart' underneath one of the products, and the button shows up just fine, but it says "The product combination does not exist." I have checked and double checked. I took the item #845532 and put that in the item ID slot, inputting the name of the product EXACTLY as it is in the ejunkie admin panel, and it still doesn't work.
