>To me it looks like it's looking for a Mexico address that includes the city and zip code all in one line and parsing/splitting it out if it finds it. I'm having issue figuring how exactly the mEr is called upon, can someone help?

Actually, I think it's looking for an address not in Mexico and parsing city, state and zip from it. mER holds an error message, but the code you showed doesn't do anything with that error message.
