I am trying to set up a query which includes running totals of my data so that I can make a cumulative graph in access. I have set up the formula: Production Standard - Running Total: DSum("[Production Standard]","M151-1A by Month (with standards)","Date <= #" & [Date] & "#") which is successful in creating a running total but I need it to only use data between a specific start and end date. My query is set to only display data between a start and end date but the running total includes all of the data. Is there a way to write in both criteria in this formula?
