Function Test(D As Double) As Variant If D < 0 Then Test = CVErr(xlErrValue) Else Test = D * 10 End If End Function This function will return a #VALUE! it only like writing to singular items. You can even use ADO to create stored procedures in Access - I believe these will be invisible to the UI ("very hidden" queries, as it were). xlErrRef (= 2023) returns a #REF!
