A problem with a script running after possibly running too many times?

Ok so, I have 2 scripts one is a local that is inside of a tool and inside of it is a global script, in the local script there are 2 values, "Done" and "Busy", "Done" doesn't really has a use. Anyways, the job for the local script is to fire the remote event that is inside of the global script only when I say the word "Duro" doesn't matter if it is in caps or not, and when I click while having the tool equipped, and to pass 2 arguments: the Mouse's hit and Mouse's hit position. Once the global script runs with the OnServerEvent event of the remote event it supposed to do ray casting with a beam shooting from the tip of the tool, it works just fine but, there is a small problem, sometimes randomly the script won't shoot the beam, it happens randomly ususally when I spam "Duro" and click (the local script is named duro btw), there are the scripts:

LocalScript:

local wand = script.Parent
local inc = script.Name
local owner, Connect
local Player = game.Players.LocalPlayer
Mouse = Player:GetMouse()


function Setup()
for i,p in pairs(game.Players:children()) do
if p.Character == wand.Parent then
print("Found owner of wand!")
if Connect ~= nil then Connect:Disconnect() end
Connect = p.Chatted:Connect(PlayerTalked)
owner = p
end
end
end

function PlayerTalked(words)
print("Someone talked!")
if string.find(words:lower(), inc:lower() ~= nil) and wand.Parent == owner.Character then
print("Casting the spell ''" ..inc.. "''")
script.Busy.Value = false
script:WaitForChild("Aqua eructo"):WaitForChild("RemoteFunction").OnClientInvoke = function()
    return
end
script["Aqua eructo"].Disabled = false
for i,v in pairs(script.Parent:GetChildren()) do
if v:IsA('LocalScript') then
print("it's a local")
local s = v:WaitForChild("Busy")
    if s.ClassName == "BoolValue" and s.Name == "Busy"  and s.Parent ~= script then
	print("Horray")
        local Busy = s
        Busy.Value = true
end
    end
end
if owner.Character.Torso:FindFirstChild("Torso") then return end
if owner.Character.Humanoid.JumpPower == 0 then return end
print("Really?")
enabled = true
wand.Activated:Connect(function()
local Mousehit = game.Players.LocalPlayer:GetMouse().Hit
local Mousehitp = game.Players.LocalPlayer:GetMouse().Hit.p
if script.Busy.Value == true then 
script["Aqua eructo"].Disabled = true
end
if script.Busy.Value == false then
if enabled == true then
	enabled = false
if not script["Aqua eructo"].Disabled == true then
script.Done.Value = false
script["Aqua eructo"].RemoteEvent:FireServer(Mousehitp,Mousehit)
end
end
end
end)
end
end
wand.Equipped:Connect(Setup)

Script:

	script.RemoteEvent.OnServerEvent:connect(function(Player,Mousehitp,Mousehit)

		if (hit) then
			laser:Destroy()
		end
		
		curDistance = (curDistance + (pos - oldPos).magnitude)
		
		-- Apply fade effect to laser as it approaches max distance from < 75 studs:
