How can I make MaxHealth equal to Endurance?

^ Title

I'd like to make my Max Health equal to the player's endurance

In the workspace there is a script, script contains as follows:

game.Players.PlayerAdded:connect(function(player)
	player.CharacterAdded:connect(function(character)
		character.Humanoid.MaxHealth = "What Here?!"
	end)
end)

The what here part is what I'd like to change, I'm not sure how to refer to Endurance.Value

In the ServerScriptService there is the system script which currently contains (working code):

game.Players.PlayerAdded:connect(function(Player)
	local Data = Instance.new("IntValue",Player)
	Data.Name = "Data"
	local XP = Instance.new("IntValue",Data)
	XP.Name = "XP"
	XP.Value = 0
	local Level = Instance.new("IntValue",Data)
	Level.Name = "Level"
	Level.Value = 1
	local Strength = Instance.new("IntValue",Data)
	Strength.Name = "Strength"
	Strength.Value = 1
	local Endurance = Instance.new("IntValue",Data)
	Endurance.Name = "Endurance"
	Endurance.Value = 50
	local Agility = Instance.new ("IntValue",Data)
	Agility.Name = "Agility"
	Agility.Value = 1
	
	game.Players.PlayerAdded:connect(function(player)
		player.CharacterAdded:connnect(function(character)
			character.Humanoid.MaxHealth = Endurance
		end)
	end)
	
	XP.Changed:connect(function() XPChange(Player,XP,Level,Endurance) end)
	
end)

function XPChange(Player,XP,Level,Endurance)
	if XP.Value >= Level.Value*10 + 100 then
		XP.Value = 0
		Level.Value = Level.Value + 1
		Endurance.Value = Endurance.Value + 50
	end
end
