"when i step off it doesnt stop the teleport it still makes both chartacters teleport onto the mat I want to make sure when one of the character steps off the mat it ends the script compeltely please show me a step by step instruction on how to do this included with a script update"

Sure, I understand your requirement now. You want the script to stop running when one of the characters steps off the mat. This can be achieved by using a while loop that checks if the player is still on the mat. If the player steps off the mat, the loop will break and the script will stop running. Here's how you can do it:

```lua
-- server script
local mat = script.Parent
local teleportDistance = 7 -- change the distance to 7 studs
local teleportDelay = 5 -- add a delay of 5 seconds

local function onPartTouch(otherPart)
    local player = game.Players:GetPlayerFromCharacter(otherPart.Parent)
    if player then
        local otherPlayer
        for _, p in pairs(game.Players:GetPlayers()) do
            if p ~= player and p.Character and (p.Character.HumanoidRootPart.Position - mat.Position).Magnitude <= mat.Size.Magnitude then
                otherPlayer = p
                break
            end
        end
        if otherPlayer then
            while true do
                wait(teleportDelay) -- add a delay before teleporting
                -- check if the player is still on the mat
                if (player.Character.HumanoidRootPart.Position - mat.Position).Magnitude > mat.Size.Magnitude then
                    break
                end
                local direction = (player.Character.HumanoidRootPart.Position - otherPlayer.Character.HumanoidRootPart.Position).Unit
                player.Character.HumanoidRootPart.CFrame = CFrame.new(mat.Position + Vector3.new(0, mat.Size.Y, 0) + direction * teleportDistance, mat.Position - direction * teleportDistance)
                otherPlayer.Character.HumanoidRootPart.CFrame = CFrame.new(mat.Position + Vector3.new(0, mat.Size.Y, 0) - direction * teleportDistance, mat.Position + direction * teleportDistance)
            end
        end
    end
end

mat.Touched:Connect(onPartTouch)
```

This updated script adds a while loop that continuously checks if the player is still on the mat. If the player steps off the mat, the distance between the player and the mat will be greater than the size of the mat, and the loop will break, stopping the script from running.
