Ideas as to why my Google Map is not showing?

I’m working through this tutorial on how to establish a Google Map that populates with locations from a custom DB. I almost have something working but nothing shows up.

Tutorial:

There seems to be an error in the JS as follows: GBrowserIsCompatible is not defined.

I am using Chrome and Safari on the Mac as well. Any suggestions on how to address this?

It’s working now. Nevermind.

If you do not mind,
Could you post how you solved it so This thread can act as a reference for others?

Thank you,
