Can anyone figure out why this wouldn't work when[First Stop Time] is null.

First: IIf([Dispatch]=0 Or IsNull([First Stop Time]) Or [First Stop Time]=0 Or [First Stop Time]>=[Dispatch],"No","Yes")

Thanks!

Try this. It wil handle the Null condition properly.

First: IIf([Dispatch]=0 Or Nz([First Stop Time])=0 Or Nz([First Stop Time])>=[Dispatch],"No","Yes")
