I am new to spreadsheets and have no training. My knowledge is very limited. Screenshots of the spreadsheet I’m creating are attached. I am attempting to total all miles and fuel by state on sheet “Quarterly IFTA Report” for all the sheets between the sheets “Start” and “Stop” Additional sheets between “Start” and “Stop” are added regularly. I have read that I can use =SUMIF. But when I do so I can only get it to work for a single sheet. Can someone please help me with the correct method and formula to accomplish this? I would greatly appreciate the assistance.
