How would I make a function fire after another function has been fired?

I need to know this because I'm trying to make an ax that works by mouse1down and onTouched but I don't know how to do that. Heres the current script (from toolbox)

wait(1)
------------------------
axelvl = 1
treeMoney = 25
resettime = 2
------------------------

Tool = script.Parent
ting = 0 --this is my debounce

function hit()
	print("hitting")
	local anim = Instance.new("StringValue")
	anim.Name = "toolanim"
	anim.Value = "Slash"
	anim.Parent = Tool
end

function onActivated() 
	if not Tool.Enabled then
		return
	end
	
	Tool.Enabled = false
	hit()
	Tool.Enabled = true

end 

function onTouched(hitt)
--	print("touched something")
	if ting == 0 then
	ting = 1
	if hitt.Parent.Name == "Tree" then
--	print("touched tree")
	user = game.Players:findFirstChild(Tool.Parent.Name) --find the player that carries the axe for later moneygiving

	hitt.Parent.hit.Value = hitt.Parent.hit.Value - axelvl --deal damage to the tree 

	if hitt.Parent.hit.Value < 1 and hitt.Parent.Timber.Value == 0 then --check if the tree is felled
		user.leaderstats.Money.Value = user.leaderstats.Money.Value + treeMoney --add money to the dude with the axe
		hitt.Parent.Timber.Value = 1 --this declares the tree "felled" and makes sure nobody else can get money from it
		wait(resettime)
	else
		wait(1)
	end
	end
	ting = 0
	end
end

Tool.Activated:connect(onActivated)
connection = Tool.Handle.Touched:connect(onTouched)

So how would I make function ontouched(hitt) only fire when a mouse1down function is fired?
