How do I remove an object in room 6 from room 7?

[the cranky hermit]

Here's what I would like to accomplish. There is an object 0 in room 6. If you use object 0, it is removed from the room and you gain inventory item 1. In room 7, there is a button. If you push the button, if object 0 exists in room 6, it is removed from the room and you get a message informing you. If you push the button and item 1 is in your inventory, it is removed from your inventory and you get the same message. If object 0 is not in room 6, and if item 1 is not in your inventory, you get no message. How would I accomplish these?
