This is probably a simple one, but I have little experience with regexps. I have a string that must only contain letters and/or numbers and be between 6 and 20 characters long. So far, I have [a-zA-Z0-9]{6,20} but that only gets me 1/2 way there.
Thanks!

^[a-zA-Z0-9]{6,20}$
The ^ matches the beginning o the string and the $ the end.

Um. No, it shouldn't. I doesn't
Are you trying to FIND a valid string, an invalid string, or are you trying to FIX an invalid string?

Thanks, but doesn't quite do it. I should probably clarify what I need. I
left out an important word last time.

When someone adds or resets a password, I'm trying to make sure what they
entered matches the pattern I described below.

When I tested ^[a-zA-Z0-9]{6,20}$ against "astrjuh" it matched, but not
when I tested it against "astrjuh$".
What version of CF are you using?
