Basically, it uses an IIM with a property. The property broadcasts on “Check For Item” when it’s changed. A checker receives on “Check for Item” and checks if the amount of the item is one. If so, it is wired to an item granter that grants -1 of the item. The emergency meeting should also be started by the checker if the check passes.
could you walk me through it? (again sorry)

this is what I have right now
What is the IIM wired to?
the tag zone, so when tagged, it activates, and also when tagged, it grants 2 grapes
Why 2?
because you can only hold 1 grape, it requires you to drop one
after tagging someone
Ok. So make the property trigger the checker. The checker should check if the player has 1 grape.
IIM, or a checker?
The checker should be triggered by the property.
ok, got it, what should the property be triggered by
The IIM edits the property.
ok, after that?
Then, the checker should check if the player has 1 grape. If they do, then it should broadcast to an item granter that takes a grape away.
ok, got it
Make a trigger that receives on the same channel as the item granter. It should broadcast on the channels that triggers the emergency meeting.
witch one?
The one taking the grapes away.
with wires, would it be so that when check passes, it triggers
Also, here is what I have so far
