How come my Combat attack will only attack once and then next time you use it it won't do dmg?

There were no errors in the output but I couldn't figure out the problems;

Here's my full script;

local Combat = script.Parent
local Animation = game.ReplicatedStorage:WaitForChild("CombatAnimation")
local Fighting = false
local Damage = script.Parent:WaitForChild("Damage")
local StaminaUse = script.Parent:WaitForChild("StaminaUse")
local CurrentStrength = Combat.Parent.Parent:WaitForChild("Status"):WaitForChild("CurrentStrength")
local CurrentStamina = Combat.Parent.Parent:WaitForChild("Status"):WaitForChild("CurrentStamina")
local CurrentStaminaStat = Combat.Parent.Parent:WaitForChild("Status"):WaitForChild("CurrentStaminaStat")
print("All Variables Defined")

function onActivation()
    if CurrentStamina.Value >= 10 then
        Damage.Value = 6
        print("Combat Tool Activated")
        local Humanoid = Combat.Parent:WaitForChild("Humanoid")
        local anim = Humanoid:LoadAnimation(Animation)
        anim:Play()
        print("Playing Animation")
        CurrentStamina.Value = CurrentStamina.Value - StaminaUse.Value
        CurrentStaminaStat.Value = CurrentStaminaStat.Value + StaminaUse.Value
        CurrentStrength.Value = CurrentStrength.Value + StaminaUse.Value
        print("Added and Subtracted all stats")
        Combat.Parent:WaitForChild("Right Arm").Touched:connect(function(Hit)
            if not Fighting then
                Fighting = true
                Damage.Value = 6
                if Hit.Parent:FindFirstChild("Humanoid") then
                    Hit.Parent:WaitForChild("Humanoid").Health = Hit.Parent:WaitForChild("Humanoid").Health - Damage.Value
                    if Fighting then
                        Fighting = false
                        Damage.Value = 0
                        wait()
                        print("Combat Right Arm Has been completed")
                        Combat.Parent:WaitForChild("Right Leg").Touched:connect(function(Hit)
                            if not Fighting then
                                Fighting = true
                                Damage.Value = 6
                                if Hit.Parent:FindFirstChild("Humanoid") then
                                    Hit.Parent:WaitForChild("Humanoid").Health = Hit.Parent:WaitForChild("Humanoid").Health - Damage.Value
                                    wait()
                                    if Fighting then
                                        Fighting = false
                                        Damage.Value = 0
                                        print("Completed")
                                    end
                                end
                            end
                        end)
                    end
                end
            end
        end)
    end
end

Combat.Activated:connect(onActivation)

Any ideas of what I did wrong or what went wrong? Any feedback will help.

Note; It worked once but the next time I activated the tool it did no dmg but the animation played.
