18:38 Demonica [20]: hi
18:38 Eryn: Hello Demonica. Do you want to buy any spell runes?
18:38 Demonica [20]: bp uh
18:38 Eryn: ~HE SAYS NOTHING~
18:38 Demonica [20]: yes
18:38 Eryn: It was a pleasure doing business with you.

Why doesn't he ask me if I want to buy the bp for 3k? I'm using Jiddo's advanced NPC System and Mokerhammers buyContainer script.
