Hi Don, thanks for the response. I should have made it clear that this data
is in a pivot table and I want to use the Custom Forumla feature to generate
the percentage field automatically.

Have a PT like this:

Month Who
Jan 3.5
Feb 2.2
Mar 3.3
Total 9.0

I want to add a new custom field or whatever on the right of this that will
show each item as a percentage of the total so I see 2.2 and 25% next to it.

Thanks
Rory
