Trying to add one to current count upon usage

Hey guys try to make a simple quest system. Below is a table for a current quest. I am trying to make it so when a user uses an entity the activator’s count goes up 1. I tried:

activator.count = activator.count + 1



quests[4] = {
	name = "Find the Ancient Book!",
	qtype = "collect",
	complete = 1,
	killhook = function( ent, count )
		if checkIfBook( ent ) then
			count = count + 1
			if count >= 1 then
				return { count, true }
			else
				return { count, false }
			end			
		else
			return { count, false }
		end
	end
}


There’s not enough code here to help much - what is ent? Where are you defining the activator? When you are returning { count, bool }, what does that do?
