XSS Filter Stripping "1" Off of the Ends

Oh for crying out loud -- good eye! I put the "TRUE" in the wrong place and didn't even notice. I've been trying to figure out what is wrong with this for about an hour now. It's always nice when a typo actually works instead of throwing an error.

I'm embarrassed but grateful -- thanks for your help!
