Tim,
I'm not sure that you've fully explained the validation that you're looking
for, but I'm going to assume the following for a moment--You want to allow
all strings that have at least one alpha, followed by exactly one hyphen,
followed by at least one more alpha.
If so, here is a usable regex:
^[a-zA-Z]+-[a-zA-Z]+$
Here's the breakdown:
^ start of line
[a-zA-Z]+ One or more alphabetic characters
- the literal hyphen character
[a-zA-Z]+ One or more alphabetic characters
$ end of line
Here's a good reference:
