My sheets are all categorized by date, and I want to be sum individual cells on each worksheet on one final summary worksheet. For example, if cell A1 on each sheet was units sold and I wanted to see how many total units were sold between Jan-04-08 and Jan-16-08 my formula on the summary sheet would be:
=SUM('Jan-04-08:Jan-16-08'!A1)
But I want to be able to easily modify what dates my summary sheet shows so I tried using the function:
=SUM(INDIRECT("'"&N14&":"&N15&"'!A1"))
where N14 was the starting sheet and N15 was the ending sheet. It keeps giving me #REF! however and I can't figure out why and don't know if this is something I can fix. Any help would be greatly appreciated.
