Option button click with if else statment

I am trying to execute a program using if else statement on an option button to open a userform on a command button click. The following userforms are named as drilling, milling and so on. The trouble I am having is, the vba tell me my if else statements are wrong could some one show me the right way if i am doing something wrong

Private Sub Ok_Click()


 If Drilling.Value = True Then Drilling.Show
 ElseIf Milling.Value = True Then Milling.Show
 ElseIf Turning.Value = True Then Turning.Show
 ElseIf Reaming.Value = True Then Reaming.Show
 ElseIf Boring.Value = True Then Boring.Show

End If

End Sub

Because you put the first IF/THEN on one line, that ends the entire IF statement. You must put the action after the THEN on another line in order to use ELSEIF. For example:

Private Sub Ok_Click()
If Drilling.Value Then
    Drilling.Show
ElseIf Milling.Value Then
    Milling.Show
ElseIf Turning.Value Then
    Turning.Show
ElseIf Reaming.Value Then
    Reaming.Show
ElseIf Boring.Value Then
    Boring.Show
End If
End Sub

You don't need the "= TRUE" part in each test, since an option button should be either True or False by nature.

You have a name conflict if you have ActiveX option buttons with the same names as forms. If that's the case, name the buttons as optDrilling, optMilling, etc.
