FactoryTalk View - Parameters on VBA

Hi all, i'm creating a ComboBox using Visual Basics on Factory Talk View SE. My issue comes when i tried to add items to the ComboBox. But this items must be values from a P - Parameters List.

How can i do this? I have a little code created but doesn't work. Anyone can help me?

Thanks in Advanced

PD: Here is my actual code.

Private Sub Display_AnimationStart()

Dim List As StringList
Dim Msg1 As String

    Set List = Me.TagParameters
    Msj1 = Lista.Item(1)
    
    ComboBox1.AddItem (Msj1,1)

End Sub
