VLookup - Duplicate Lookup Values

[BobbM424]

I am trying to use a vlookup formula to pull information from one sheet to another. The problem is that my ID column has many duplicate ID's but each ID has a different quantity and vlookup always pulls the quantity from the first ID in the array. For example:

ID Original Vlookup
Lugo 1 1
Pedroia 2 2
Ortiz 3 3
Ramirez 4 4
Drew 5 5
Youkilis 6 6
Lowell 7 7
Varitek 8 8
Crisp 9 9
Lugo 4 1
Pedroia 5 2
Ortiz 6 3
Ramirez 7 4
Drew 8 5
Youkilis 95 6
Lowell 3 7
Varitek 2 8
Crisp 1 9

Total 176 90


Is there any way I can fix this so that it uses the correct quantity for each ID and not just the first quantity it encounters?

Thanks a lot for your help.

How do you determine which one is the correct quantity to return? Or do you want to ADD them All together?

If you want to add them all together, use sumif.

=vlookup("Lugo",A:B,2,FALSE) - will return 1
=sumif(A:A,"Lugo",B:B) - will return 5

I am trying to sum the 2nd column. the 3rd column is just what vlookup gives me, basically I need a function that will cause the 3rd column to match the second column.
