MYSQL: calling a stored procedure inside another

I am aware that this has been asked in a plethora of variations on this site, but i have become thoroughly stuck in implementing my own variation. I think it has something to do with my understanding of the DECLARE statement and @variables in stored procedures.

In short, I am trying to create a function to populate a stats table using a function I have already written to sum up a member's attendance, to be able to not recalculate this every time an overview is asked for... ( I am not opposed to just including it in this procedure, but I would like to be able to call it separately as well, and i like the idea of code reuse.

My initialization of the stats table:

drop table if exists core_stat_totals;
create table core_stat_totals (id  int unsigned,  half_year char(7),  num_attendance int default 0);
truncate core_stat_totals;
insert into core_stat_totals select id,  '', 0 from core_medlemmer ;
select * from core_stat_totals;

and my procedure:

drop procedure if exists updatestats;

delimiter //
create procedure updatestats()
begin
    DECLARE yr int default 2008;
    DECLARE dt int default 1;
    DECLARE done INT DEFAULT 0;
    DECLARE childResult int default 0;
    DECLARE userID int unsigned;
    DECLARE cur CURSOR FOR SELECT id FROM core_medlemmer;
    DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = 1;

    truncate core_stat_totals;
    open cur;
    repeat
      read_loop: LOOP
        FETCH cur INTO userID;  
        IF done THEN
          LEAVE read_loop;  
        END IF;
        call getStats(userID, concat(yr,'-01-01'), @result);
        insert into core_stat_totals(id, half_year,num_attendance) values(userID, concat('q1_',yr),@result);

      END LOOP;

      SET yr = yr + 1;
    until yr = 1 + year(current_date()) end repeat;
  CLOSE cur; 
  select * from core_stat_totals;
end
 // 

EDIT: I solved a couple of issues with cursor not being declared and unopen cursors, now my procedure keeps returning things, which is essentially the inner procedure returning them, and getting 2014: commands out of sync.

I am working in mysql workbench against Mariadb 10.1.30
