Excel - List view element in a form

I have a form (a cash - book). There is a field called "Konto" (account). I would like that when this filed gets the focus, that a user form with a list view element opens. The list view element has 3 columns and can have about 200 lines. The data shown in the list view element are coming from a separate other worksheet called Konten (accounts). When the user is selected one of the lines of the list view element, the number of the account should be written in the field "Konto" of the form. The columns of the list view element should have a sortation (up/down). After a line is chosen (Click on ok), the user form should close automatically.
