Why is this Remote Event sending a nil Player variable?

game.Players.PlayerAdded:connect(function(player)
    --stuff
    workspace.Comm.CreateMenu:FireClient(player)
end)

workspace.Comm.CreateMenu.OnClientEvent:connect(function(player)
    --stuff
    local meta = player.Meta
end)

As you can see, i'm sending the Player variable consistently through these remote events, yet on line 8, it says that the Player variable is nil. halp
