[request more eyes to see the error :)] Mangos Npc trainer

[Veldor]

Hello Friends. I got a little problem and i don't find this fu*king error
I know this should be posted in the Datapack Forum but they are currently down
Tryed already hours to fix this but will not work !

I made Npc Trainers but i don't know why they don't train me spells.

My Npc looks like this.


And my npc_trainer looks like that.

INSERT INTO `npc_trainer` (`entry`, `spell`, `spellcost`, `reqskill`, `reqskillvalue`, `reqlevel`) VALUES
(50003, 2138, 3000, 0, 0, 22),
(50003, 2139, 4000, 0, 0, 24),
(50003, 2948, 3000, 0, 0, 22),
(50003, 3140, 1800, 0, 0, 18),
(50003, 3552, 14000, 0, 0, 38),
(50003, 5143, 200, 0, 0, 8),
(50003, 5144, 1500, 0, 0, 16),
(50003, 5504, 100, 0, 0, 4),
(50003, 5505, 400, 0, 0, 10),
(50003, 5506, 2000, 0, 0, 20);

Hope someone can help me resolve my problem
