[JD] Buying Pet food problem

I remember last time i post this problem & this still occurs when you want to buy pet food Wangzo Grape.

I set my trigger to buy wangzo grape when it is 0(finished)

my character is teleport to town going skylord and it will warp to Sun Stream to buy the item sold by pet tamer totto.

But after it runs back to it spot my character don't buy wangzo grape.

anyway now i know the time when i need to buy manually wangzo grape, i just inform this problem.

have a nice day to all
