Thanks Cetin, and yes, it could be better, I was wondering if this is possible with a single query, I'll do the test to see what's the better approach. Thanks again!

Select iAgentId, Month(dDate) As Month, Year(dDate) As Year, Sum(yAmount) As YTot ;
    FROM cMovs ;
    GROUP By 1,2,3 ;
    into Cursor crsSums ;
    nofilter

Update cAgent ;
    SET yMonth = t2.YTot ;
    FROM crsSums t2 ;
    WHERE t2.iAgentId = cAgent.iid ;
    AND cAgent.nMonth = 1 And cAgent.nYear=2005 ;
    And t2.Month = cAgent.nMonth ;
    AND t2.Year = cAgent.nYear
