Report summar

So I want to get a summary on a field but with consideration to another field

so like I want to sum of volumes for dealer age = 'New'

[SUM(<UniDACQuery."volume"> <UniDACQuery."dealer_age"> = 'New',MasterData1)] I know this is not correct but what is the correct way if it is possible?

This one works

[SUM(IIF(<ADOQuery."CountryId">=10,1,0),MasterData1)]

Worked perfectly, thank you
