Single Select Multi Columns Listbox to Populate value in Textbox

Hello Gurus,

I have a multi-columns listbox which is single-select and also i have two textboxes.
How can I display the value of the second column in my second textbox?

I have the below code that display the columns in my Listbox:

Private Sub UserForm_Initialize()

Dim lngMyRow As Long

    For lngMyRow = 2 To Cells(Rows.Count, "B").End(xlUp).Row
    
        If StrConv(Range("T" & lngMyRow), vbUpperCase) = "WAITING FOR APPROVAL" Then

            With ListBox1
                .ColumnCount = 3
                .ColumnWidths = "125;60;110"
                .AddItem
                .List(.ListCount - 1, 0) = Range("B" & lngMyRow)
                .List(.ListCount - 1, 1) = Range("I" & lngMyRow)
                .List(.ListCount - 1, 2) = Range("F" & lngMyRow)
            End With

        End If
        
    Next lngMyRow


  End Sub

And below to display the 1st column in my 1st textbox.

Private Sub ListBox1_DblClick(ByVal Cancel As MSForms.ReturnBoolean)

UserForm1.txt_sc.Value = ListBox1.Value

End Sub

Thanks in advance!
