[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
