I have 100 worksheets with all rows and columns structured the same. The first 20 sheets are designated as "Summary" sheets and the last 80 sheets contain the "Data" to be consolidated (sum) on the appropriate first 20 "Summary" sheets. I need the values from each cell in the range "D11:O340" from all "Data" sheets to be sum totaled on the appropriate "Summary" sheet cell range "D11:O340" if the "Data" sheet cell "A1" equals the "Summary" sheet cell "A1".
For example, if "Data" sheets 21, 45, 48, 67 & 95 (could be any sheet) have the same cell "A1" value as "Summary" sheet 1 cell "A1", the values from each cell in the range "D11:O340" from each "Data" sheet are sum totaled on "Summary" sheet 1 cells "D11:O340"
Example
on Sheet 1
A1 = 15
B1 = =SUM(Sheet2:Sheet4!B1)
on sheet 2
A1 = your value
B1 = IF(A1=Sheet1!A1,A1,0)
the same setup on each additional sheet.
