Thanks Radzmar...good eye for detail. I was jostling about the subforms in an attempt to structure them differently and pasted in the wrong code in the discussion.
I have tried the form.ready, layout.ready and initialize....they all had the same effect. I'm able to make visible invisible elements but am not able to make visible hidden elements. Seems the code should be the same for both of them. I made sure to try your code, and it had the same effect. Do hidden elements require something in addition to invisible elements?
I will take a look at your link to the developer specs, I appreciate that link. As you can tell, I'm pretty new with adobe forms.
