Execute Query on List Box change

[AllegraAccess]

I have a list box (1L) in a form (1F) that list member IDs from a table. Then I have a query (1Q) that use (1L) member ID to get data from a table another related table. When I change the 1L and run the query 1Q the results is correct. So I added a new list box (2L) in form 1F that show the results of the query. When I open the form 1F the 2L is populated correctly by the query. Here is my problem. I need to have list 2L update when I change 1L. Here is what I did. I created an On Change event for 1L that has a code Me.2L.Requery, but nothing happens.

For some reason Access disabled this function. I noticed a warning about it. When I enabled it the function worked.
