        map<id, opportunity> omap = new map<id, opportunity>([select id, name, createdbyid, accountid from opportunity]);
         for(opportunity o : omap.values()){
                 system.debug(omap.get(o.id).name); //This works find and give me the opp name
             if(amap.containsKey(o.AccountId)){
                  system.debug(amap.get(o.accountid).name);
