what do you mean by "running total"?

[sambasiva_ravuri_tcs_com]

Running Total means, for example sam is having sal of 25 as a first record and kemp is having sal of 35 and steve is having sal of 40.

I should get the output like for Running Total as

25 - for the first record.

60 - (25 +35) for the second record

100 - (60 +40) for the third record and so on.
