Thank you for your attention to this Zack!
The answer is "yes" and "no".
I am now able to modify one of our forms. Luckily it's the one that we're using...yay! Unfortunately the formatting doesn't seem to be working correctly. I can modify the form (using "Apple" style now), but the result on the web page doesn't match the form builder. For instance if the form is set to 300px wide it looks fine in the form builder sample but on the web page the text (email, name, etc.) all moves to the right of the boxes - even though the alignment in the form builder is set to center. The only way to avoid that is to make the form narrower (200px), which forces the text to the center. Hope that makes sense.
Also, I cannot build/save any new forms. After modifying any of our other existing forms and clicking on "Save" the original layout returns.
I also cannot delete any existing forms. When I try I get this error message:
"The form could not be deleted. The form may have already been deleted."
Finally I believe there is supposed to be a "Clear all" option? If so, it's not available for some reason.
Here is where we're using the form currently:
Note that the "Sign up" button is still left aligned for some reason.
So it's better, but still problematic.
Thanks again for your very hard work on this, it's truly appreciated.
