If you do an average of all of the possible values in the particular
category, Excel will ignore the blanks (not yet played), so you should be
okay.

I am doing a Darts score sheet in excel 2003. I have "game scores", "game
shots", "game average", "games played", "(sum)total scores", "(sum)total
shots", "(sum)total average", improvement increase\decrease percentage,
and I
have even done a "bar chart". What I can't work out is how to formulate a
column for "progressing average".
The only way I can get "progressing average" at the moment is by
formulating
ONE cell as "(sum)total score"/"(sum)total shots" then entering the
result
manualy into the corresponding cell so that the players can see how they
are
averaging (up or down).
Any solutions please? don't make it too hard and complicated, I'm only
"self
taught"
over about 5yrs and I'm still finding out lots of things.
