The running totals are the totals from the previous 24hr period. Records do have a specific time on them. I have a report that shows me totals for the previous 24 hour period and I need to keep that, but underneath I also need a breakdown of totals for three shifts out of the 24hr total.

The 24hr total I got by entering my parameter when prompted upon first opening the report.

I tried taking your formula idea and inserting my reference table where necessary, but that didn't give me any relevant information. It only showed up, seemingly at random, "Shift 1" or "Shift2" etc. and thats all it gave. It did not list the total from shift 1 and shift 2 and shift 3 like I needed.

I apologize, for my ignorance. I am learning as I go, but I appreciate your help.
