[AccessD] Query is to complex

Access says this query is to complex and of course cannot run it. I need some suggestions on how to do this better. Several queries,  VBA? 
Thanks

SELECT [qry Manifold Oil Production last 90 Days].Manifold, [qry Manifold Oil Production last 90 Days].ProductionDate, [qry Manifold Oil Production last 90 Days].Oil1, [qry Manifold Gas Production Last 90 Days].Gas1, [qry Manifold Water Production Last 90 Days].Water1, IIf([Oil1]=0,Null,[Gas1]*1000/[Oil1]) AS GOR1
