Sword giver arena and sword disappear when exiting?

You keep the tool in server storage. Then when the players enter the arena you cycle through them using a for loop and give them swords, at the end you cycle through them again, removing all the tools. Please at least attempt to script something it helps us out and it will personally help you get better with scripting, overall though a good question and explanation.

--When players are teleported to the arena
-------Variables
players{} = game.Players:GetPlayers()
SWORDNAME = "" --Put your sword name here

-------Main Script
for i = 1, #players do
    newsword = game.ServerStorage:WaitForChild(SWORDNAME):Clone()
    newsword.Parent = players[i].Backpack
end

--When Players leave the arena
for i = 1, #players do
    players[i].Backpack:WaitForChild(SWORDNAME):Destroy()
end

Let me know if this doesn't work or you need more help.

I used a free model teleport blocks for the teleporting, and this is the script I did for the one block that takes the players into the arena. What did I do wrong? (I also put "Sword" in lighting.)

modelname="teleporter1d"
------------------------------------

players{} = game.Players:GetPlayers()
SWORDNAME = "Sword" 

for i = 1, #players do
    newsword = game.ServerStorage:WaitForChild(SWORDNAME):Clone()
    newsword.Parent = players[i].Backpack
end



function onTouched(part)
    if part.Parent ~= nil then
    local h = part.Parent:findFirstChild("Humanoid")
        if h~=nil then
            local teleportfrom=script.Parent.Enabled.Value
            if teleportfrom~=0 then
                if h==humanoid then
                return
                end
                local teleportto=script.Parent.Parent:findFirstChild(modelname)
                if teleportto~=nil then
                    local torso = h.Parent.Torso
                    local location = {teleportto.Position}
                    local i = 1

                    local x = location[i].x
                    local y = location[i].y
                    local z = location[i].z

                    x = x + math.random(-1, 1)
                    z = z + math.random(-1, 1)
                    y = y + math.random(2, 3)

                    local cf = torso.CFrame
                    local lx = 0
                    local ly = y

                    wait(3)
                    script.Parent.Enabled.Value=1
                    teleportto.Enabled.Value=1
                else
                    print("Could not find teleporter!")
                end
            end
        end
    end
