First Available Unique Number

I'm terrible at Filemaker's calculations. I'm needing to auto-enter a serial number, but it needs to be the lowest available unique number. So, say for example, a record gets deleted, I would like the next new record to get it's number.

What would this calculation look like? Say we have a library with call numbers 1-10 and the record with call number 5 has been removed. The next new record needs to get call number 5 instead of 11.

Thanks for any help you guys can give!
