Of course that should be:
=D2/SUMIF($B$2:$B$200,B2,$D$2:$D$200)

In L2 enter =C2/SUMIF($B$2:$B$200,B2,$C$2:$C$200) adjust the sumif

Since you guys have been very helpful before, I thought I'd ask if you
could help me do a SUMIF (or other) solution to the following

Col "A": player name
COl "B": team name
Col "D": attempts

about 300 rows of data, not ordered by team.

What I want in Col "L" is the %age of attempts the player has had on
his team, the players will be mixed up, not in team order, so I want
to be able to see immediately without sorting that a player has had
34.5% of the attempts on the team he plays for

Can this be easily done?

cheers !
