I prefer to use cursor, and refill it each time user will pick up new value from the first list. Remember Listbox2.requery to get new appearance.

*** in Form.Designer
With Thisform.Listbox2
.RowSourceType=2
.RowSource=""
Endwith
*** when refreshing
With Thisform.Listbox2
.RowSource=""
*** use one of following two lines
.RowSource='offyear' && if offyear is literal alias or
.RowSource=offyear && if offyear is variable storing alias
.Requery
Endwith
