UserForm unload multiple selections from ListBox

[Tmoske]

I have a userform that has a listbox named Instructor. From the listbox the user can select multiple Instructors in the list. I want these selections to populate my spreadsheet. Right now it only populates the first item in the list no matter what selection is made. What am I doing wrong?

Cells(NextRow, 9) = Instructor.List

Thanks for the help,
