TL;DR: weird error, what's going on?
Uncaught TypeError: boolean is not a function
First of all, it points to line 148, where I call display(). Maybe I'm looking at the wrong file? What's going on?!
P.S. I was working on an XML import/export thing, but I don't think it's the problem. Ignoring it might be a better option.
