I have a form that the user selects which report to run and sets the criteria for the report. Criteria choices are start date, end date, Group and sub group. The issue is that a group can have any number of sub groups and sometimes only specific sub groups are selected. I've used a Listbox to display the subgroups and set the multiselect property to Simple. The problem is that in the query that is the source for the report how do I set the criteria. I've tried forms!frm1!List10. I also tried In forms!frm1!list10 Neither works. How do I use a multi-select listbox in a query to get only those subgroups that were selected?
