How Do I Change A Player's Max Health Depending On Their LeaderStats?

I Have Just Recently Started Coding In Roblox But I Can't Figure This One Out

This Is The Code I Used:

while true do
	
local Health = script.Parent.Humanoid.MaxHealth
local PlayerStrength = script.Parent.Parent.Parent.Players.LocalPlayer.leaderstats.strength

Health = PlayerStrength.Value

end)

Bearing In Mind I Have Put This In A LocalScript And I Dont Know Where To Put The Script.
