THANK YOU! That did it. I had removed the quotes surrounding the whole thing, but didn't even consider removing the double quotes. THANKS!
A second question, if you don't mind. While trying to solve this problem I read some worrisome things about xml not being supported by some export options Construct 2 has. Like CocoonJS, and some others. Is that something I should worry about? Should I switch to a different format? Like JSON?
Thanks!
