Sum varying length blocks of data

i need your help immediately as i m facing severe problem in adding excel data ,.
Actually i have few sets of data and i want to show the result(sum) in next blank cell to every set of data. I m showing it through example below..

eg:- set1 :

Score
20
19
15
suppose this is the frst set , hence i want the resultant or sum i,e 54(20+19+15) just below 15, the blank cell just next to 15 highlighed

set2:
Score
78
191
131
now suppose in this bunch or set the sum would be 400, thus it should be displayed below the cell showiing 131 value highlighed

and most importantly all these sets are in single sheets and they are in thousands,
attached is the test sheet .....

Hi,

Please take a moment to read the forum rules and edit your thread title accordingly.

I would also advise uploading a sample workbook rather than asking people to give out their email address.
