Thanks for the info, Rick but unfortunately, the MLS numbers currently vary between five and six digits. If that Real Estate market stays this bad, they may go to seven or eight digit numbers.
However, is it possible to create a list from the query "Photos" and Remove a character from the right side of the field?
