Short Answer Text Box/Results Slide

Hi, Cheryl.

You're very welcome! I'm glad we're getting closer to what you have in mind!

I didn't notice the issue with Post-quiz #3 at first because it's dependent on where you click, as the top half of the button is being covered by the last option of the multiple choice. But, as Walt mentioned above, because you have a textbox and a button, it can cause problems. 

A quick fix is to make sure they're together and on the top of the timeline:

However, a better solution, echoing Walt's suggestion, is to either edit the text of the button or create a shape as the button. When you insert a new button, you can type the text directly on it:

I hope this helps!
