I'm new to VBA and need some help.

I have a worksheet with User forms. I have code that launches and locates my first user form when I double click within a range of cells. I would like to add a second range that will launch the second user form

my Code
Private Sub Worksheet_BeforeDoubleClick(ByVal Target As Range, Cancel As Boolean)
If Not Application.Intersect(Target, Range("B6:B206")) Is Nothing Then
Cancel = True

With DIMENSION_TYPES_LIST

.StartUpPosition = 0
.Left = Application.Left + (0.5 * Application.Width) - (0.5 * .Width) - 500
.Top = Application.Top + (0.5 * Application.Height) - (0.5 * .Height)
.Show

End With
End If

End Sub
My second range is c6 to c206 and the form name is frmdimensionbuilder

Thanks

Steve
