Npcs Coding big problem

hi, i have conquer prserver version 5165 blabla bla

so i'm trying to change some prices

so this video will show you how i'm doing to change the price, and tell me what's wrong in, because when i enter in the game(efter changing the prices) i see nothing changed

do u have ADHD ?? or ur parents punishes you?? u already wrote it o.O

Just post the code here, we cannot see anything from the video.

Are you doing it via seller npc or shop npc?

i'm changing the price of "breeder" who sell +7 to +12 steeds , (not a shop)
