Percentage/PERCENTRANK

I have a large amount of data that I would like to calculate percentages
for. Specifically Economic Data, which breaks out Total US Sales, Then
each states sales. I would like to have a new column which expresses
each state's percentage of overall US Sales.
But when I copy my formula down the column, say C2/C1*100, it copies
C3/C2, C4/C3 and so on, instead of each state divided by C1. any help
appreciated, I tried PERCENTRANK, but I must be using it wrong.
Thanks,
Larry

Dollar signs ($) in range references "lock in" that part of the reference.

Try this:
=C2/$C$1*100
Then copy that formula down

Does that help?
