    Dim trythis As Boolean
    Dim testit As Boolean

    trythis = False

    If (Sheets("Sheet1").Range("A1").Value = 1) Then
        testit = testingRoutine(trythis)
        If (trythis) Then

            Sheets("TESTING").Range("A1").Value = 0
        End If
    End If

End Sub

Private Function testingRoutine(ByRef trythis As Boolean) As Boolean

    Debug.Print "Ran Function"
    trythis = True

End Function
