Subject: Simple regex question
I'm in need of some regex help. I am working with a cfinput and I need a
pattern for regex validation that does the following:
Field can be blank but if filled out has to be exactly 17 characters which
are a combination of letters and numbers (VIN number)
Know this is simple but Google seems to be failing me this morning.
Thanks,
Rick
