column based total

Hi,

How can i get the total of the particular COLUMN accross various rows that is

i should get the total like (1,2)+(2,2)+(3,2)+(4,2) +…



I tried using the format :[[1,2]]+[[2,2]]+… but this is not working,

Actually this must work , but the indexes of row and columns are zero based
