Trigger Debugging Help

[PCPharaoh]

I'm trying to make a -repick command, so that a player can repick their race in the TD that I'm making. The trigger is supposed to order all the player's towers to sell, thereby destroying them, then destroys the person's tower builder, and finally creates a hero selection building for the hero. I would also appreciate any leak help I could get. I'm not sure if I covered all of them or not.
