I have a set of textbox controls on a userform called n1,
n2 etc.

I have a common function that needs to handle each of
these controls after they are updated.

I want the name (n1, etc..) to be passed to the function
and substituted into the code that then runs against this
control. How to I pass the control name into the function?
What I have does not work!

' control n1
Private Sub n1_AfterUpdate()
ValidateNumber("n1")
End Sub

' control n2
Private Sub n2_AfterUpdate()
ValidateNumber("n2")
End Sub

'Function (example to test value passed
Private Function ValidateNumber(nBox)
MsgBox nBox.Value
End Function
