Hi

With the help Pete UK of an earlier thread used the following formula

sumproduct(--(sheetname!A1:a20="GA01")--(sheetname!B1:b20=105))

What I now want to do is use the indirect function with sumproduct in a
summary sheet

sumproduct(--(""&c1&"!A1:a20,a6)--indirect(""&c1"!b1:b20=105

Cell A6 contains the first criteria (GA01)
Cell C1 contains the shhet name

Help would be appriciated as it is not working !
