Howcome my gamepass more health script doesnt work properly?

When you buy gamepass you have 100 more health, but when your in the game your health is half? How come?

gps = game:GetService("GamePassService");

id = script:WaitForChild("GamePassID"); EH = script:WaitForChild("ExtraHealthAmount");

game.Workspace.ChildAdded:connect(function(char) h=char:FindFirstChild("Humanoid") if h~=nil then plr=game.Players:FindFirstChild(char.Name) if gps:PlayerHasPass(plr, id.Value) then h.MaxHealth=EH.Value h.Health=EH.Value end end end)

I also placed two IntValues, that say ExtraHealthAmount, and GamePassID
