So, if you put "a" in A1 of sheet4, you want B1 to show 4 (the sum of
all the a's from the other 3 sheets?) If so, put this in B1 of Sheet4:

=IF(A1="","",IF(ISNA(VLOOKUP(A1,Sheet1!A:B,2,0)),0 ,VLOOKUP(A1,Sheet1!
A:B,2,0)) + IF(ISNA(VLOOKUP(A1,Sheet2!A:B,2,0)),0,VLOOKUP(A1,S heet2!
A:B,2,0)) + IF(ISNA(VLOOKUP(A1,Sheet3!A:B,2,0)),0,VLOOKUP(A1,S heet3!
A:B,2,0)))

Copy this down as far as you think you need it.

Hope this helps.
