Eudemons Purchase

i'm trying to make my own private server and play with my friend,the problem is,where should i change to make eudemons purchase available in my server

when ever i try to buy eudemons from eudemons purchase,it shows null,but in EO there is price for them.....

what npc or place are you trying to buy these eudemons from and what eudemon are you trying to buy?

awwww,urm,its not from any npc,but from the system itself

try go to shopping mall --> purchase ->manual set (auto set need egg) -->pick any egg
-->submit on any

in my pserver the price didnt show for all pet
