UPDATE: Damn. I hate when I do all that work to post something and then find out it's something entirely unrelated. Nevermind.

I know for a fact that there is only 1 occurrence of '&' in the TextRequestMessage variable, but when I strip it out, my message fails. I'm sure it's because of the ampersand, but I need to strip it out. It looks like it does strip it, but then it causes the message to fail. If I manually remove that one ampersand, then the message goes through fine. Where I'm trying to strip it out is in this string:

SUNSHINE SPINE & PAIN PA OP

This is the TextRequestMessage variable before the STRTRAN():
