Will the countif function work? Say on the summary sheet you have the
product in cell a1, then you could count the matching products in each
years sheets to get the total.
=countif(Year1Sheet!A:A,Summary!a1)+countif(Year2S heet!A:A,Summary!a1)
Where the product is in the A column of the YearSheets.
