Excellent! Yes I can confirm you've fixed it. Very pleased I found your plugin now (can't remember where I first saw it though, certainly wasn't here because I watched a video of you installing it). Many thanks for providing the fix.
Now I know that adding content CAN be done, I'm even more determined to get a fix for my VAT issue http://wordpress.org/support/topic/vat-breakdown-on-product-page?replies=1 . Fancy coding another plugin? ;o)
