A script that teleports the player on touched. wont work?

 local debounce = false
script.Parent.Touched:Connect(function(hit)
    local player = game.Players:GetPlayerFromCharacter(hit.Parent)
    if debounce == false then
        if player.Atlantis.Value ~= nil then
            if player.Atlantis.Value == true then
                hit.Parent.HumanoidRootPart.Position = Vector3.new(game.Workspace.Teleporttoatlantis.Position.X, game.Workspace.Teleporttoatlantis.Position.Y, game.Workspace.Teleporttoatlantis.Position.Z)
                debounce = true
                wait(5)
                debounce = false
            end
        end
    end
end) 

The fault is very likely at line 5 and 6. Roblox doesn't put any values within the Player in Players. Your best bet is to put your "Atlantis" value within "game.StarterPlayer.StarterPlayerScripts" and instead do the following:

if player.PlayerScripts.Atlantis ~= nil then --Do not use "if player.Atlantis.PlayerScript.Value ~= nil" as this means something else
if player.PlayerScripts.Atlantis.Value == true then --Here you're comparing its value
