Hi to all.
My objective is to make an entity which opens a Gui with only one slot to store items.
I made all files needed for this. When y right-click on the entity it opens the Gui and i can put objects in the slot, the problem is that the object is not stored inside the slot, if I press Shift + right-click the same.
I don't know what's wrong.

These are my Container and Entity files:
