Whats wrong with this OnChatted script? [Unsolved]

bin = script.Parent

BlastRad = 30

keyword = {"kamikaze", "Boom"} -- Things that will trigger the explosion when said

print("Kamikazi Script Loaded")

function explode(player)
    print("exploding player")
    character = game.Workspace:findFirstChild(player.Name)

    local explosion = Instance.new("Explosion")--Creates The Explosion.
    explosion.Position = character.Torso.Position --Where The Explosion Is.
    explosion.BlastRadius = BlastRad
    explosion.Parent = game.Workspace --It Has To Be Visible Correct?

end

function onChatted(msg, recipient, speaker)

    msg = string.lower(msg)

    for i=1,#keyword do
        if (msg == keyword[i]) then explode(speaker) end
    end

end

function onPlayerEntered(newPlayer)
    newPlayer.Chatted:connect(function(msg, recipient) onChatted(msg, recipient, newPlayer) end) 
end

game.Players.ChildAdded:connect(onPlayerEntered)
