Having troubles creating a specific TRIGGER in MySQL So I am trying to implement a trigger in MySQL that is triggered once a new user is registered. 
The relation of my tables are:
USER_ACCOUNTS has primary key USER_ID.
RACE_TRACKS has primary key RACETRACK_ID.
HIGHSCORES has as foreign_keys USER_ID and RACETRACK_ID.

The trigger I am trying make, must create records in HIGHSCORES table in a way that each NEW.USER_ID has a record for each of the RACE TRACKS (RACETRACK_ID).

Using phpMyAdmin database management tool I came to this point.

BEGIN
DECLARE trackID INT;
DECLARE done INT DEFAULT FALSE;
DECLARE trackCURSOR CURSOR FOR SELECT USER_ID FROM INSERTED WHERE USER_ID = NEW.USER_ID;
DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = TRUE;

INSERT INTO HIGHSCORES SELECT trackID FROM RACE_TRACK;

OPEN trackCURSOR;
    REPEAT
    FETCH trackCURSOR INTO trackID;
    IF NOT done THEN
            BEGIN
            INSERT INTO HIGHSCORES (RACETRACK_ID, USER_ID)
            VALUES (trackID, NEW.USER_ID);
            END;
    END IF;
    UNTIL done END REPEAT;
CLOSE trackCURSOR;
END;


I am not getting any errors but when I am testing it if it works nothing happens. I am a bit confused to say the least because I do not have experience with triggers. If there is any way to enlighten me I would appreciate it.

Thank you in advance.

EDIT:
After some feedback more searching this is how my trigger looks now.

BEGIN
DECLARE v_RACETRACKID INT;
DECLARE FINISHED INTEGER DEFAULT FALSE;
DECLARE racetrackCURSOR CURSOR FOR SELECT RACETRACK_ID FROM RACETRACK;
DECLARE CONTINUE HANDLER FOR NOT FOUND SET FINISHED = TRUE;

OPEN racetrackCURSOR;

get_racetrackID : LOOP
    FETCH racetrackCURSOR INTO v_RACETRACKID;
    IF FINISHED = TRUE THEN
          LEAVE get_racetrackID;
    END IF;

    INSERT INTO HIGHSCORES (RACETRACK_ID, BEST_LAP, BEST_RACETIME_1, 
        BEST_RACETIME_2,USER_ID) VALUES (v_RACETRACKID,null,null,null 
        ,NEW.USER_ID);
    END LOOP get_racetrackID;
    CLOSE

 END;
You need to put your code in a CREATE TRIGGER statement. 

CREATE TRIGGER AddNewUserToHighscoresTable 
    AFTER INSERT ON USER_ACCOUNTS 
    BEGIN 
         &lt;insert code to run after inserts on the USER_ACCOUNTS table here...&gt; 
    END
