Thanks for the suggestion. I actually am hiding the subform and not the field directly. It seems as if any content entered into a field within a hidden subform is not collected in the response file. I can however see that the information is in fact filled in.
This is great. However I'm finding that when I use the javascript code to format the text, it also formats the caption. Is there any way to isolate the formatting to only the text field and not the caption?
