How to make a custom Health GUI that is just based off of a number?

So I am creating a health GUI that is just based on a number.

This pic should explain things: http://prntscr.com/3drmjb

Someone gave me this script: Humanoid.Changed:connect(function(Health) blah end)

So can anyone help?

well that would be very advanced by using an onTouched sword or bullet script by damage and find the number of health

It's not that hard. No functions are needed. Just put a script inside the Gui (which should be in starterpack). It's best if the script was a LocalScript.

Here's what you do:

local youtheplayer = game.Players.LocalPlayer;
local youthecharacter = youtheplayer.Character
local yourhealth = youthecharacter.Humanoid.Health

while wait () do -- goes on forever
	script.Parent.Text = yourhealth -- makes the text the same as your health. 
end
