    function that will set a specified cell to a specified value.

    Please help me.

    I am trying to write a function that will set a specified cell to a specified value. (Code is below).

    Let's say my current location is A1. In A1, I enter =SetCellValue(M2, "Bob") expecting M2 to be set to "Bob".
    Instead A1 is set to #VALUE!.
    Same with =SetCellValue("M2", "Bob"). Debugging shows that the problem occurs at the TargetCell.Value = NewValue
    Debugging also shows that TargetCell and NewValue are being passed to my function. Everything is in the same Sheet.
    I have made this as simple as I could. but I can't figure out what I am doing wrong.

    Function SetCellValue(TargetCell As Range, NewValue As Variant) 
        ' Set the value of the target cell 
        TargetCell.Value = NewValue 
    End Function

    This is working as expected given the constraints of a UDF Description of limitations of custom functions in Excel - Microsoft Support

    User Defined Functions (UDF) cannot change a worksheet, they can only return a value to the cell(s), in this case A1

    You would need to use a Sub

    The best alternative might be to use a Worksheet_Change event and that's not great

    Option Explicit
    Private Sub Worksheet_Change(ByVal Target As Range)
        Dim iRow As Long
        Dim r1 As Range
        If Target.Column > 2 Then Exit Sub
        Set r1 = Target.Cells(1, 1).CurrentRegion
        With r1
            If Target.Row > .Rows.Count Then Exit Sub
            Application.EnableEvents = False
            For iRow = 2 To .Rows.Count
                If Len(.Cells(iRow, 2).Value) = 0 Then
                    Worksheets("Sheet2").Range(.Cells(iRow, 1).Value).ClearContents
                    Worksheets("Sheet2").Range(.Cells(iRow, 1).Value).Value = .Cells(iRow, 2).Value
                End If
            Next iRow
            Application.EnableEvents = True
        End With
    End Sub

    Sheet1 has addresses and values to go onto Sheet2
