Items made on buildings

[Supermj]

Very simply, I want to make it so I can sell certain items from buildings. So I put the items under the "Items Made" because they require other buildings to be made.
But, when I play the game, it says "A valid patron must be near by."
I don't want there to be heros in my game, so I made a hero just to see if it would work. I could even sell to him. Why does this happen?

I apologize for asking this as I've been modding wc3 for a long time and have never dealt with with before.

Add the abilities "Select Hero" and "Shop Purchase Item"
The first ability allows heroes to buy items from that shop and the second allows them to sell it to that shop.
