Hello all,
Please bear with me as I'm not very knowledgeable when it comes to code. My hopeful result is to select multiple Departments from a list on a form, then run a report based on an existing query with the selections in my list as a criteria. I already have the report completed and running off the query. I've been trying to get the multi-select list working, but have some questions on Allen Browne's On Event coding for the form's button. I'm not sure exactly what parts I need to change to mine. Would someone familiar with code mind simpy highlighting the parts I need to customize for my DB to be able to run this report? Thanks in advance.
