I'd assume you're talking about the "book a consultant" link. I haven't used Thickbox, but looking at the code, it looks like it's expecting a document fragment--not a complete HTML page. You could check the response headers in http://www.energy-matters.net/form.aspx and look for the header "X-Requested-With" with a value of "XMLHttpRequest". This would tell you the request came from an AJAX request. If you find this header, you then just output the HTML fragment and leave out all the stuff outside the <body /> tag. -Dan
