Use of Control Key on a button

[Guest]

On the On_Click event, I have the following code:

Private Sub Report3Button_Click()

Dim stDocName As String
If acCtrlMask = 2 Then
stDocName = "WarehouseYTDReport"
Else
stDocName = "WarehouseErrorReport"
End If

DoCmd.OpenReport stDocName, acPreview

End If
End Sub

When I run this code, I only get one response,
stDocName = "WarehouseYTDReport"

Can someone tell me what I am doing wrong?

OOPS! I see my mistake.... I moved it to the mouse_down and it works
perfectly.
