If you’re trying to get the player model can’t you just use the Character property?
local char = localplayer.Character or localplayer.CharacterAdded:Wait()
And use that instead of the game.Workspace approach?
Thank you will try that. Hope it works. 
Sadly, that didn’t work…hmmm.
If you’re waiting for the character to be added, you’re doing it incorrectly. You’re just assigning the function to a variable. Remove that entire line and replace it with localplayer.CharacterAdded:Wait(). Also instead of indexing workspace; use either :WaitForChild(), :FindFirstChild(), or a dot.
Why are you trying to index their player model from the workspace anyway? Player objects have a Character property which holds a reference to the character. You already have a reference to the character so you don’t need to index them again here. Reuse the variable.
-- For example, use this to change WalkSpeed instead:
char:WaitForChild("Humanoid").WalkSpeed = 16
The or part of that bracket is useless because Player.Name will always evaluate to a truthy value so the other operand won’t be checked.
What are you using the charAdded variable for? You could just type
local char = localplayer.Character or localplayer.CharacterAdded:Wait()
thx you im still new to scripting
