Fill ComboBox

Good Morning everyone.
Yesterday I got help on filling a listbox from here and the problem was solved with all the great help I got, snb told me I wouldbe better off with a Combobox instead of a listbox. I changed the listbox to combobox with the new code and it only fills in one row. I'm I doing something wrong or will the combobox only fill one row from list. Looking to fill row 3,4. form2 is the one I'm working on.
Thanks
