Hi - We have a form that asks for an individual's age. Amazing what's out there.... A site called UtilMill.com lets you more or less use English and common sense to come up with a regex.
For me, I wanted 3-15, inclusive, as all that's valid - i.e., 3,4,14,15 are among those acceptable; "A7" or 22 would both be rejected.
The site said this was "the ticket;"
But when I entered it PRECISELY as above, it did not get the job done.
