I'm trying to a percent change for some fields. I have the amount increased by, and I have the previous value. So I made a new field, and asked the field calc to [Increase] / [Previous]. It fails, and gives me the following.
General error executing calculator.
ERROR 999999: Error executing function.
Failed to execute (CalculateField).
It's a fairly basic operation, and works even on a cheap calculator. Anyone know what I'm doing wrong?
