I am looking to validate that my field always starts with the following text before allowing it to be saved "inc", "sctask", "prb", "chg", or "ritm".
I have messed around with the LEFT and MID checks, but cant seem to combine multiple characters:
=AND(LEFT([Ticket Number],1)="i",(MID([Ticket Number],2,1)="n"))
Any help would be greatly appreciated!
