Can't set JumpPower....? You guys on Discord weren't usefull lol

**BIG EDIT. I'm just stupid. I had a clone of my char in workspace, with the exact name... it edited it's humanoid, not mine... **

So, i cannot change a Humanoids JumpPower (or disable it)

These are my scripts.

This script (normal) is in a seat:

local Seat = script.Parent
local Deb = false
local FreezePlayerRemote2 = game.workspace.SystemRemotes:WaitForChild('FreezePlayerRemote') --RemoteEvewt
local UnFreezePlayerRemote = game.workspace.SystemRemotes:WaitForChild('UnFreezePlayerRemote')

script.Parent.Touched:Connect(function(hit)
local player = game:GetService('Players'):GetPlayerFromCharacter(hit.Parent)
    if player then
		local Speler = player.Name
		print(player.Name)
		FreezePlayerRemote2:FireAllClients(Speler)
    end
end)

This script (below) is inside StarterCharacterScripts as a LocalScript

local FreezePlayerRemote = game.workspace.SystemRemotes:WaitForChild('FreezePlayerRemote') --RemoteEvewt
local UnFreezePlayerRemote = game.workspace.SystemRemotes:WaitForChild('UnFreezePlayerRemote')

function FreezePlayer(Speler)
print('Received')
local Humanoid = game.Workspace[Speler].Humanoid
Humanoid:SetStateEnabled(Enum.HumanoidStateType.Jumping, false)
end


function UnFreezePlayerRemote(Speler)
end


FreezePlayerRemote.OnClientEvent:Connect(FreezePlayer)

HELP?
