Prior Year missing Revenues

[james]

All, I have 5 products with revenue last year, and this year only for of them have revenue. When comparing this years revenue vs last years revenue, I am receiving the proper grand total, however the product shows up but the revenue is blank?... any ideas?

({$< Year= {$(= GetFieldSelections(Year)-1)},[Calc.Type] -= {'Forecast*'},Date={"<=$(=vMaxDate)"}>}[Amount])/Factor
