I have tried batching by filtering results by a range called "nameRange".  I can paste the code into the System Log window with some hard coded values for the dates, and it seems to work fine.  When I test in the Sandbox, I hit the query governor limit.  Any ideas?

        String[] nameRange = new String[]{'KT 045000','KT 050000','KT 055000','KT 060000','KT 065000'};
 
        For (Integer i=0; i < nameRange.size()-1;i++)
        {
            for (   User_Month_KPI__c[] UserKPIs :
                                                [
                                                select  
                                                    u.OwnerId,
                                                    u.active_accounts_actual__c,
                                                    u.APNrent_month_revenue_actual__c,
                                                    u.revenue_new_accounts_actual__c,
                                                    u.new_accounts_signed_actual__c,
                                                    u.APN_Month__c,
                                                    u.APN_Year__c,
                                                    u.Month_Start_date__c,
                                                    u.Month_End_date__c,
                                                    u.avg_rev_per_account_actual__c,
                                                    u.IPI_bookings_count__c,
                                                    u.Id
                                                from    User_Month_KPI__c u
                                                where   u.APN_Year__c = :APNYear
                                                and     u.APN_Month__c = :APNMonth
                                                and u.Name >= :nameRange[i]
                                                and u.Name < :nameRange[i+1]
                                                limit 500] )
            {   
                for (User_Month_KPI__c UserKPI : UserKPIs)
                {
                    this.getCurrentSet().put(UserKPI.OwnerId,UserKPI);
                    UserKPI.Month_Start_date__c = APNMonthStartDate;
                    UserKPI.Month_End_date__c = APNMonthEndDate;
                    
                    Records++;
                    
                        
                } // End FOR
                
            } // End FOR
            
        } // End FOR
        
        CurrentSet = 0;
