can somebody help me fix my code for speed boost with a hotkey?

So basically I'm trying to make a short speed boost when you press shift but whenever I try the script it keeps saying Walkspeed is not a valid member of Humanoid can somebody review this code for me please, I suck at scripting and I'm like 2 days into it so don't criticize me too hard ;p

uif = game:GetService("UserInputService")


uif.InputBegan:connect(function(imput)
	if imput.KeyCode == Enum.KeyCode.LeftShift then
		local plr = game.Players.LocalPlayer
		local char = script.Parent.Humanoid
		char.WalkSpeed = 25
		
		wait(3)
		
		local char = script.Parent.Humanoid
		char.Walkspeed = 16
	end
end) 

On Line 13 It Is Spelled "Walkspeed" When The Acutal Propety Is Called "WalkSpeed" With A Capital S. Its Okay If You Forget Something Like That We Were All New At One Point. From Now On Always Look At The Punctuation And Spelling. You Should Also Look At Scripting Tutorial Such As AlvinBlox Or Peasfactory Before You Start Making A Game.

You can say local char = twice but u don't need too. Also in the near future :connect() will not work. Use :Connect() and use WalkSpeed not Walkspeed. I have changed local char to my liking btw not much diffrent

uif = game:GetService("UserInputService")
local player = game.Players.LocalPlayer
local char = player.Character.Humanoid

uif.InputBegan:Connect(function(imput)
    if imput.KeyCode == Enum.KeyCode.LeftShift then
       
        char.WalkSpeed = 25

        wait(3)

        char.WalkSpeed = 16
    end
end) 

thx for reading

Hey,

Assuming this script is located in the players character(which is located in the workspace), you only made one small error.

That small error? Capitalization! On line 13, it should be WalkSpeed and not Walkspeed.

Furthermore, :connect is now depricated and :Connect should be used instead.

Cheers.

uif = game:GetService("UserInputService")


uif.InputBegan:connect(function(imput)
    if imput.KeyCode == Enum.KeyCode.LeftShift then
        local plr = game.Players.LocalPlayer
        local char = script.Parent.Humanoid
        char.WalkSpeed = 25

        wait(3)

 
        char.WalkSpeed = 16
    end
end) 

EDIT: Also, as others have said, you do not need to define char twice, once is sufficient.

You spelt WalkSpeed wrong, Speed has a Captial S. Also consider using :IsKeyDown() for a Shift Boost

UserInputService.InputBegan:Connect(function()
  if (UserInputService:IsKeyDown(Enum.KeyCode.LeftShift)) then
     --// Whatever happens here
  end
end)
