Report Calculation

Hi,

I have a report which shows data from two forms which are linked. Is it possible to do a calculation in the report?

Example

Form 1, Field = Quantity

Form 2, Field = Length

Report Fields

1- Form 1, Field = Quantity

2- Form 2, Field = Length

3- Form 1, Field = Quantity * Form 2, Field = Length

Thanks for your help
