Hi,
No there isn't any way to put a listbox in a query. Normally, you would have a form that has a lsitbox with the cirteria in it so the user can select it and then run the query.
Another way is to insert into the query a reference to the listbox on a form whcih contains the criteria you wsh to use.
Another way is to build an SQL string from values selected in a various listboxes and then run the SQL statement.
Have a good one!
