So I am attempting to sum data across multiple sheets. The idea is that if the customers name appears in column A on any of the sheets, then it will return a sum of the the numbers in column C. In effort to achieve this I entered the following into a cell:
=SUMIF(INDIRECT("'"&A331:A340&"'!A312:A450"),A2,INDIRECT("'"&A331:A340&"'!C312:C450"))
This gets me: #value. Any suggestions?
