Greetings Sawn, That is not a lot of detail info re your issue but perhaps you will find solution at www.exponenciel.com add-on called Automatic Field Calculations?
You may need to add some Opportunity fields to your Opp Layout?
Possibly explore the ACT! / Reports / Opportunity Reports / Other Opportunity Reports?
