How to give correct sword when player upgrades sword?

I need help with a Fighting Simulator I'm making. It always gives the starter sword when you upgrade the sword. Here's a few parts of the script that might be incorrect:

AutoUpdate coroutine:

local c2 = coroutine.wrap(function() -- AutoUpdate Sword
    while wait() do
        for _,i in pairs(tools)do
            if i.Name == currentSword then
                sword = i.Tool
            end
            wait()
        end
    end
end) c2()

CharacterAdded function:

plr.CharacterAdded:connect(function(char)
    wait()
    local newSword = sword:Clone()
    newSword.Parent = plr.Backpack
    newSword.Activated:Connect(function()
        if atkDebounce == false then
            atkDebounce = true
            if newSword.Name=="Rusty Sword"then
                jm.Value = jm.Value + 1
            elseif newSword.Name=="Wooden Sword"then
                jm.Value = jm.Value + 2
            elseif newSword.Name=="Metal Sword"then
                jm.Value = jm.Value + 4
            elseif newSword.Name=="Ruby Sword"then
                jm.Value = jm.Value + 6
            elseif newSword.Name=="Diamond Sword"then
                jm.Value = jm.Value + 10
            elseif newSword.Name=="Demonic Sword"then
                jm.Value = jm.Value + 15
            elseif newSword.Name=="Godly Sword"then
                jm.Value = jm.Value + 20
            elseif newSword.Name=="Infinity Sword"then
                jm.Value = jm.Value + 50
            end
            wait(1)
            atkDebounce = false
        end
    end)
end)

Sword Variable Update (when upgrading sword):

if currentSword=="Rusty Sword"then currentSword="Wooden Sword"elseif currentSword=="Wooden Sword"then currentSword="Metal Sword"elseif currentSword=="Metal Sword"then currentSword="Ruby Sword"elseif currentSword=="Ruby Sword"then currentSword="Diamond Sword"elseif currentSword=="Diamond Sword"then currentSword="Demonic Sword"elseif currentSword=="Demonic Sword"then currentSword="Godly Sword"elseif currentSword=="Godly Sword"then currentSword="Infinity Sword"end

Please help me out! Many people are waiting for this project to be done, and I'm rushing to get it done!
