ListBox2 selection must be based on ListBox1 selection

I have 2 List boxes on 2 different user forms. Each list box has the same list of customers. I always use the first list box to view information for a particular customer and then go to the second list box to view additional information for that customer. When I select the list boxes, the first customer is always highlighted. When I select the second list box, I would like the customer to be highlighted based on the selection of the first list box. If I was viewing the 5th customer on list box1, I would like the 5th customer to be highlighted when I select the 2nd list box. This is the code to view the 2nd list box.

Thanks in advance.

Is it possible to achieve what I want? I think this is the line that must change.
