Firstly I'm a total newb to excel (and access for that matter LOL)
I have almost 25,000 rows of data and I'm a little scared LOL

its a basic set up, Total, Passed, Rejected ect ect across the top with the
info below.

example...

Date Total Passed Rejected
1/2/05 123 100 23
1/4/05 324 320 4
1/6/05 97 96 1

I need a fifth column showing a percentage of passed.
but I don't know how to do this with out entering the formula 25 thousand
times :-(

Please help

Also would really love to be pointed towards an easy to understand
instruction site for access.

Thank you all,

Chad
