custom user field error, please help

[Live Free]

I'm trying to add my first custom user field on the latest version. I added about 100+ options. When I go to save I get this error:

"
The following error occurred:

Please enter an ID using only a-z, A-Z, 0-9, and _ characters."
My field id is simply "location"
It is all lower case, one word, on spaces, yet I still get the error. What might cause this? I'd really hate to have to re-type all 100+ fields...
Thanks in advance.

Ah, I assumed it was the field id. I had a few dashes in the left color that were causing the problem. Thanks!
