[RE-POSTED] [ADVANCED] How come this script functions once and the second time it fails?

Summary of what I'm trying to do; I'm making a combat tool where if you hit someone you do damage. It all worked perfectly the first time but the second time it fails. I used the print method and did find something but I don't know how to fix this. I posted this many times now and was never answered so I decided this probably is on the harder side to answer.

For more info on the game; https://web.roblox.com/games/756392385/New-Project Here's my ENTIRE script;

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

function onActivation()
    if CurrentStamina.Value >= StaminaUse.Value then
        print("Combat Tool has been activated and player has enough stamina")
        local AnimeHumanoid = CombatTool.Parent:WaitForChild("Humanoid")
        local LoadAnime = AnimeHumanoid:LoadAnimation(Animation)
        LoadAnime:Play()
        print("Animation Has been Loaded, playing...")
        CurrentStamina.Value = CurrentStamina.Value - StaminaUse.Value
        wait()
        CurrentStaminaStat.Value = CurrentStaminaStat.Value + Damage.Value
        Damage.Value = Damage.Value + CurrentStrengthStat.Value
        CurrentStrengthStat.Value = CurrentStrengthStat.Value + StaminaUse.Value
        print("Stats have been calculated")
        CombatTool.Parent:WaitForChild("Right Arm").Touched:connect(function(Hit)
            if not Fighting then
                Fighting = true
                print("Fighting Became True For The Right Arm")
                if Hit.Parent:FindFirstChild("Humanoid") then
                    Hit.Parent:WaitForChild("Humanoid").Health = Hit.Parent:WaitForChild("Humanoid").Health - Damage.Value
                    Fighting = false
                    CombatTool.Parent:WaitForChild("Right Leg").Touched:connect(function(Hit)
                        if not Fighting then
                            Fighting = true
                            print("Fighting Became True For The Right Leg")
                            if Hit.Parent:FindFirstChild("Humanoid") then
                                Hit.Parent:WaitForChild("Humanoid").Health = Hit.Parent:WaitForChild("Humanoid").Health - Damage.Value
                                Fighting = false
                                print("Completed")
                            end 
                        end
                    end)
                end
            end
        end)
    end
end

Combat Tool has been activated and player has enough stamina
Animation Has been Loaded, playing...
Stats have been calculated

Every time I use combat tool it will print "Combat Tool has been activated and player has enough stamina"

so look for those parts to know what printed the first time and second time

Here's the part that stopped at the second time;

CombatTool.Parent:WaitForChild("Right Arm").Touched:connect(function(Hit)
            if not Fighting then
                Fighting = true
                print("Fighting Became True For The Right Arm")
                if Hit.Parent:FindFirstChild("Humanoid") then
                    Hit.Parent:WaitForChild("Humanoid").Health = Hit.Parent:WaitForChild("Humanoid").Health - Damage.Value
                    Fighting = false
                    CombatTool.Parent:WaitForChild("Right Leg").Touched:connect(function(Hit)
                        if not Fighting then
                            Fighting = true
                            print("Fighting Became True For The Right Leg")
                            if Hit.Parent:FindFirstChild("Humanoid") then
                                Hit.Parent:WaitForChild("Humanoid").Health = Hit.Parent:WaitForChild("Humanoid").Health - Damage.Value
                                Fighting = false
                                print("Completed")

It printed "Stats have been calculated" at the end but didn't print anything else so this part probably went wrong.

Please help me! I need; - Feedback - Explanations - Why it doesn't work - How to fix - A script that will work the same way - Help Thank you for any feedback.
