[AccessD] Using the recordset of a list control

Mark,

Yes, the rowsource is a sql (sql="select bla, bla..":
Me.lstListe.RowSource=sql), and on the form I have a combo box that will
update the list rowsource according the selection made.
Fields(1) and Field(2) are normally not Null.
Another fact: befor doing the calculation, I tried to requery the list, to
ensure th existence of a recordset, but it seems to be unefficient!

Thanks for your help.
