Hello. Is there any way that I can improve this formula? There are two lookups HOUSE DIVISION and NATIONAL DIVISION and everything else is the same.

=INDEX(INDIRECT("'["&$B$11&".xls]Sheet1'!$E$77:$E$851"),MATCH("HOUSE DIVISION",INDIRECT("'["&$B$11&".xls]Sheet1'!$B$77:$B$851"),0))+INDEX(INDIRECT("'["&$B$11&".xls]Sheet1'!$E$77:$E$851"),MATCH("NATIONAL DIVISION",INDIRECT("'["&$B$11&".xls]Sheet1'!$B$77:$B$851"),0))
