E-mailing Notes using JavaScript

Hi! I'm trying to send notes to an e-mail using this tutorial, but somehow I'm hitting a roadblock. When I click my e-mail icon, nothing happens. I've tried opening and publishing Stephanie's course on my computer, and the e-mail function works then. I've also tried troubleshooting by copy/pasting her exact button and code into my file, but that also doesn't seem to work. Would someone mind checking my code to make sure this looks correct? I feel like something must be wrong in how I have my file set up, but I'm super new to Articulate (I've used Lectora for 3 years and recently changed companies/authoring tools) and can't figure out what I'm doing wrong.

I appreciate any and all assistance!
