Why won't the Instance parent to the character?

I'm making a running script for all platforms. It took me like 3 days to make because of bugs and stuff. For the running script for controller, I made it so it puts a boolean value inside of the player's character that sees if the player is running or not. This is so when the player presses a button on the controller, it makes you run, but then when you press the same button after, it stops running. This is the part of the script I used to add the boolean value.

local char = game.Players.LocalPlayer.Character or game.Players.LocalPlayer.CharacterAdded:Wait() 
game.Players.LocalPlayer.CharacterAdded:Connect(function() 
boolean = Instance.new("BoolValue") 
	boolean.Parent = char 
	boolean.Name = "run"
	boolean.Value = false 
end)

In the code I said, "boolean.Parent = char", yet the value doesn't appear anywhere. It's probably still parented to nil, and I don't know why.

hey you! have you ever heard of enes? if you are in trouble, better call enes!
