How can I modify the code below to reference a non-active worksheet, I do not
want to use 'Activeworksheet'

Dim dX As Double, dCount As Double
Worksheets("test").Activate
sSelected = Me.Cbo1.Value
dCount = 0
If IsError(Application.Match(sSelected, ActiveSheet.Columns(1), 0)) Then
frm1.Hide
frm2.Show
End If
For dX = 1 To ActiveSheet.UsedRange.Rows.Count
If Cells(dX, 1).Value = sSelected Then
Me.Cbo2.AddItem Cells(dX, 2).Value
dCount = dCount + 1
End If
Next
End Sub
