With ComboBox3
.Clear
.AddItem ("OB 1 to 3")
.AddItem ("OB 4 to 5")
.AddItem ("OB 6 to 9")
End With
Case Is = False
With ComboBox3
.Clear
.AddItem ("OB 11 to 13")
.AddItem ("OB 14 to 15")
.AddItem ("OB 16 to 19")
End With
End Select
End SubIf
Private Sub OptionButton1_Change()
ComboBox2.Clear
If OptionButton1.Value = True Then ' an option button can have 2 values true (selected) and false(not selected)
With ComboBox2
.Clear
.AddItem ("1 to 3")
.AddItem ("4 to 6")
.AddItem ("7 to 9")
'add as many items you need
