Saving Storyline Variables to a PDF

So I was running into trouble with this until, on a whim, I decided to reference jquery and a few other libraries for the heck of it (in addition to the jsPDF and FileSaver pieces) mentioned in the post. I'm happy to report it works now! I'm not sure why this worked, exactly, but here are the script tags I added. When I have some time I'll see if I can isolate which references are making it happen and which aren't. In the meantime... IT WORKS!
