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?
