How would I dynamically change the Thank You Message (TYM) after submitting a Form?  I would need to trigger the message, that contains a hyperlink to another Form, based on a Drop Down list entry selection of the current Form being filled out.

We've tried using JS to populate a hidden field on the form and used that variable in the TYM.

Values that do not have any HTML code work, but placing plain text HTML code with the thought that the TYM section would interpret it causes submission errors.
