User notes that they can print and email

Hello, I have another question on the Notes element of this thread. I'd like to create a Notes panel that learners can show or hide throughout the training, using it to type in their notes as needed and emailing all their notes to them at the end.

I have the email piece down thanks to this thread.The issue I'm running into is that I can't figure out a way to allow learners to show the Notes panel whenever they want to.   I placed a Notes panel with a show/hide button on a Master Slide, but when I use that layout with multiple layers that show/hide one at a time as the learner clicks a series of buttons, the Notes panel disappears with the first button click, as does the Note panel button.

If you can figure out how to do this - or help me identify what I am doing wrong - I'd appreciate it!

Thanks.
