Simplest way might be to get CF to work out the 11 prohibited values and
then search for them (. IN ('23T256472544','23T256472545'...) )

Subject: Checking strings

How would I check a string such as:
23T256472549 and make sure there are no other entries in the database
within 5 digits of that? So, 23T256472554 would not be allowed and
23T256472544 would not be allowed (and the inbetweens as well).

Thanks!
