[Repub] why is my anticheat not working?, gives really sus error.

Why Is my Code not working? This fires an remote event:

while wait(0.05) do
	local Char = script.Parent
	local Speed = Char.Humanoid.WalkSpeed
	local Tbl = {}
	table.insert(Tbl, Char.Name)
	table.insert(Tbl, Speed)
	game.ReplicatedStorage.AntiCheatLab:FireServer(Tbl)
end

And this is the Code that recieves it:

local Replicate = game.ReplicatedStorage.AntiCheatLab
Replicate.OnServerEvent:Connect(function(tbl)
	local charName = tbl[1] -- Error is here, line 3
	local speedVal = tbl[2]
	local PlLoad = game.Players:WaitForChild(charName) 
	local ChLoad = game.Workspace:WaitForChild(charName)
	local CharObj = game.Workspace:WaitForChild(charName)
	if CharObj.Humanoid.WalkSpeed ~= speedVal then
		game.Players[charName]:Kick("===")
	end
end)

Error 1 is not a valid member of Player "Players.Ferrarimami" - Server - Script:3
