how to add rows

[Rasoul Khoshravan]

The best way is to use sumif. This function adds values of cells, when other
cells meet a condition. Look to help for this function
Merging cells is not a wise solution.
I have an excel sheet in which rows will look below

---------------------------------------------------------------------------­---------------

ACTIVITY STARTTIME STOPTIME TOTALTIME
---------------------------------------------------------------------------­-------------------

srikanth 11/2/2006 11.46 11/2/2006 11.48 0.02
ravikanth 13/2/2006 11.48 11/2/2006 11.50 0.02
srikanth 14/2/2006 10.48 11/2/2006 11.48 1.00
ravikanth 15/2/2006 10.30 11/2/2006 11.00 0.50


i want to merge two rows if the activities have the same name....and
add the totaltime for those two activities..that means that output
should look like below which i will save in another excel file.
