Won't heal me if I get damaged?

local heal = game.Workspace.lomo0987.Humanoid.Health
local max = game.Workspace.lomo0987.Humanoid.MaxHealth

while wait() do
if heal < max then
heal = max
end
end

Currently in a game using kohls admin and trying to so a small script that will heal me almost instantly.

Hum = game.Workspace.Player1.Humanoid

function Heal()
if Hum.Health < Hum.MaxHealth then
Hum.Health = Hum.MaxHealth

end
end

Hum.HealthChanged:connect(Heal)
