Private Server: NPC for give P skills

Hi, I'm with a problem with the NPC to give P skills.
When the player goes to the teachers learn skills, after they go to special NPC to take P skills, but that doesn't work, doesn't give P skills or another level skill. But when I'm go with a GM char that NPC give me the P skills!

Code:
