Hello, I can't work out why:
If (IsNull(DLookup("[Module]", "Table1", "[Module]=" & Me.Combo23)))
Is generating a syntax error when the code I based it on:
If (IsNull(DLookup("[External Examiner]", "Together", "[External Examiner]=" & Forms![Copy of Add EE Assignment]!Combo21)))
Isn't.
Any ideas? Thanks.
