You don't need JS for this. Just add display logic to individual choices.

Wow! That was much easier, thanks so much! But here's a tougher one at least for me... how do I only display an additional email field to be completed by a respondent when they need it instead of how I have it set up in the attached? I can't get the above method to work since there is no embedded data or other to use.

You could set this email problem up with a lead-in question asking "How many professors would you like an accommodation letter sent to?" This gives you the trigger you need for the question displayed. Your Display Logic would be statement-by-statement, driven by the answer from the lead-in question.
You could get fancier with a button in the question that increments an embedded data integer and drives your statement display logic dynamically, but that's way more complex and I don't think the juice is worth the squeeze in this case.
Any questions, let me know. I can probably mock something up for pretty quickly.

Yep, I will probably go with the first option and keep it simple, great idea this forum rocks!
