Hello, Basically, I'm having issues trying to setup a system where a party member can learn a skill by buying and using an item that gives them the skill. I have most of it worked out however I'm trying to make the skills/items, class specific. So, for example: Skill #1 can only be learned by Class #1. Skill #2 can only be learned by Class #2. etc However, no matter where I try to look on the forums or try for myself, it doesn't work. I have tried to use advice from posts such as these: http://forums.rpgmakerweb.com/index.php?/topic/13041-class-id-in-common-events/ http://forums.rpgmakerweb.com/index.php?/topic/14148-common-events-for-an-item-class-changing/ http://forums.rpgmakerweb.com/index.php?/topic/19731-creating-an-item-that-will-level-up-the-target-actor-only/ and this is what I estimate is supposed to work: However, whenever I try to test it, I get this error message: Could anyone give me some pointers as I'm completely lost at this stage. Thank you in advance.
