I'm trying to figure out how to construct a formula to extract certain
information.

The text may look like one of the following:

Safeway Store # 711 - Mill Valley, CA
Jake's Marketplace - Oakland, CA

I am wanting to take the city portion (between the "- " and the "," and put
it in another column. The number of characters will vary and I'm not sure
how to do this. Thanks for any help.
