If you have a list of IDs on the first column of each sheet and you
want to sum values in the second column for each ID on the summary
sheet, try filling down:
=SUMPRODUCT(SUMIF(INDIRECT("'"&Shts&"'!a:a"),A1,INDIRECT("'"&Shts&"'!
b:b")))
Where Shts is your range containing the sheet names.
One way to get a list of all IDs on to the summary sheet is to choose
Data > Consolidate with the options:
Function: Count
References: Sheet1!$A:$B, Sheet2!$A:$B, Sheet3!$A:$B, ...
Use Labels in: Left column
then click OK. If you use "Sum" for the summary function you should
get the same results as the formula above.
Another possibility is to use a PivotTable with the "multiple
consolidation ranges" option.
