Calculating Percentage

[ssimons]

Hey all. I'm having a problem figuring out how to calculate a percentage. Here's the senario. I have a database that I am doing summary based on Vendor and I need to figure out what percentage the Vendor total is of the grand total. Can anyone offer some advise on how to do this?

Thanks.

Use another summary field, defined as Fraction of Total of the summarized field.
