I have a workbook with several sheets named Jan, Feb, Mar, Apr, May, Jun, Jul, etc. I'd like to be able to dynamically reference a range of sheets to sum in another sheet. For example, I have a Summary sheet that has a cell E3 that contains "Jun" and E4 contains "Dec". I'd like to sum cell E10 in the sheets Jun through Dec. If I change E3 to Jan, I'd like the formula to sum Jan through Dec. If I change E4 to Apr, I'd like it to sum Jan through Apr.
This is what I've tried:
=sum(Indirect("'"&$E$3:$E$4"&&"'!E10")
It doesn't work to sum values in E10 across the sheets in E3 and E4.
