Chest and Command

[Alecs 1]

Hello!
1 Does anyone know how I can do is open a chest of special_item_group but if you have "10 spaces" can not open it?
2 I want to know how do you give a command like 71020 items in inventory (like command / full_item but to give you the items in inventory not equip).

Thank you.

Why don't you try to make a quest instead of that for such chest?

If that is not your real request, it should be an if statement that checks the space before opening a chest and dropping the items on the ground.
