The code in the bowser and the code in DW are quite different. It appears that the extra DIV tag needed to go prior to the Span that holds the button element. In the browser your suggestion worked, but the edited code in DW caused an error and didn't actually show the expected change in the browser
I will have a go at deleting the cache and seeing if this helps although I had deleted it only a few days ago to try to reduce the amount of times Data Assist was crashing DW.
