Punching Damage doesn't work right????

local player = game.Players.LocalPlayer
local mouse = player:GetMouse()

local Combo = 1
local enabled = true
local CanDamage = false

mouse.KeyDown:connect(function(key)
if key == "q" then
        if Combo == 1 then
if not enabled then return end
enabled = false
            local a = player.Character.Humanoid:LoadAnimation(script.Punch1):Play()
wait(0.5)
            Combo = 2
enabled = true
mouse.KeyDown:connect(function(key)
if key == "q" then
                if Combo == 2 then
    if not enabled then return end
enabled = false
                       local b = player.Character.Humanoid:LoadAnimation(script.Punch2):Play()
        wait(0.5)
        Combo = 3
enabled = true
mouse.KeyDown:connect(function(key)
if key == "q" then
                if Combo == 3 then
    if not enabled then return end
enabled = false
                       local c = player.Character.Humanoid:LoadAnimation(script.Kick):Play()
        wait(0.5)
        Combo = 1
enabled = true
end

game.Workspace:FindFirstChild(game.Players.LocalPlayer.Name)['LeftHand'].Touched:connect(function(part)
    local human= part.Parent:findFirstChild("Humanoid")
    if human then
        if human.Parent.Name~= game.Players.LocalPlayer.Name and CanDamage == false then
    CanDamage = true
            human:TakeDamage(10)
            wait(1.2)
            CanDamage = false
        end
    end
end)
game.Workspace:FindFirstChild(game.Players.LocalPlayer.Name)['RightHand'].Touched:connect(function(part)
    local human= part.Parent:findFirstChild("Humanoid")
    if human then
        if human.Parent.Name~= game.Players.LocalPlayer.Name and CanDamage == false then
        CanDamage = true
            human:TakeDamage(10)
            wait(1.2)
            CanDamage=false
        end
    end
end)
end
end)
end
end
end)
end
end
end)

Basically I tried to change the CanDamage Variable to false instead of true i switched places between them and nothing seems to work It does damage even when the animation is not playing.

Help me please.
