Hi,

I have 3 worksheets and want to combine a vlookup to find the sum of the
unique criteria. I can get it to work with 2 spreadsheets but not 3.

The formula i am using is: =IF(ISERROR(VLOOKUP($A99,'sheet1
v4'!$A$3:$AR$103,COLUMN(AR99),FALSE)),VLOOKUP($A99 ,'Sheet2
v4'!$A$3:$AR$98,COLUMN(AR99),FALSE),VLOOKUP($A99,' Sheet1
v4'!$A$3:$AR$103,COLUMN(AR99),FALSE))

Example:

Sheet 1
Apple 2
Banana 5
Orange 11

Sheet 2
Mango 4
Banana 5
Pear 7

Sheet 3
Apple 2
Grape 1

Summary Sheet
Apple 4
Banana 10
Orange 11
Pear 7
Grape 1

I must be missing something simple but can't figure it out, any help would
be appreciated
