I used a DSum to get a running sum/cumulative total by month in a query. Works for one item, but when using for more than 1 it accumulates everything, even though grouping by item by month. So then, I created a report from the raw data andused a Running Sum. That works great, but I need to add a chart to the report, and I see no ability to use running sum or base chart off report. Looking for a solution to either a running sum in a query that doesn't work for just one item or a way to get a running sum on a chart in a report. Thanks!
