Google maps “'a' is not defined error”

Question

I am getting that "'a' is not defined" error that a lot of people seem to be getting.

Some people point to the geocoder, but in this link there shouldn't be any geocoder lookup because its a straight to lat/lng/zoom. I've tried everything I can think of but just can't seem to get rid of the error.

Any ideas would be very much appreciated!

Figured it out!

I was trying to remove a listener that wasn't set yet.
