Can someone hep me with obby Checkpoints? The one I use takes 2-120 minutes to respawn

This is the code i used.

function ot(hit)
if hit.Parent ~= nil then
local player = game.Players:playerFromCharacter(hit.Parent)
if player ~= nil then
if player.leaderstats.Stage.Value == script.Parent.Name - 1 then
local h = hit.Parent:FindFirstChild("Humanoid")
if h ~= nil then
if h.Health ~= 0 then
player.leaderstats.Stage.Value = script.Parent.Name
end
    end
        end
            end
                end
                    end

script.Parent.Touched:connect(ot)
