Hi Guys,

I have a table with a task code column and a count column. Im trying to add a calculated column to give me the desired result below. I need tasks 51E and 51F to be added together but the others just what they are. 

Desired Result:

Task Code	Count	Desired Calculated Column
6A	42	42
7B	24	24
51D	20	20
51E	60	100
51F	40	100

Thanks!

@Bpark1994 , Try a new column

if([Task Code] in {"51E","51F"} , sumx(filter(Table,[Task Code] in {"51E","51F"}),[Count]), [Count])
