I'm creating a database to track call drivers or reasons for customers calling in. All of this information is selected via combo boxes and stored in a table. I have a query to pull the data and a form that lets you select date parameters to filter the time you want the query to pull. Here is the problem I have a report that displays the count and percentage of the data selected from the query, but I also need to display and calculate data from the week before the time selected and also what the percentage the call driver is YTD. Does anyone have suggestions on how I could do this?
