Hi, Thanks for the reply. However, your code only seems to be any good with the actual page content you are on, not the values of a string? Remember, this data is coming through as a string (as a response from a jQuery .post() function, so the returned HTML then holds errors which may have occured - and I need to pick up on those :))
