I got an error with nil and I dont know how to solve it

Hello I get a one issue with my code

local tool = script.Parent

local player = game.Players.LocalPlayer

local char = player.Character

local humanoid = char:WaitForChild(“Humanoid”)


if humanoid then

humanoid.WalkSpeed = 50




if humanoid then

humanoid.WalkSpeed = 16



that script has to change player walk speed when item is equipped to 50

issue its dont work because of something with nil and waitforchild

Error Message:
Players.vitopencilPro2020.Backpack.Bumper Car.LocalScript:4: attempt to index nil with ‘WaitForChild’ - Client - LocalScript:4

one time its work and changed my walk speed but next time its didnt work I dont try any solutions because I dont know what I can do

Im trying to do something with it but its always dont work

Please format your code, also check if the character exists, and if it does not, then wait for it, like so:

char = player.Character or player.CharacterAdded:Wait()

Use this insted of this local char = player.Character:

local char = player.Character or player.CharacterAdded:Wait()

Also like @DasKairo said to create code format like this:


You can press contrl + E in new line or press button number 6 in new line, this button looks like this: </>. Also you can just put this ``` in start and end, in center put code you want. It makes code more readable.
