Problem with Line 6?!

Hi there! I made a Teleport GUI. And everything I made was perfect but ever since I put the ScreenGui to ReplicatedStorage because I only want it to myself. Anyway I'm having trouble in Line 6 of this Script:

spawn = game.Workspace.HouseArea
player = script.Parent.Parent.Parent.Parent

local funtcion onClicked()
    local spawnArea = game.Workspace.HouseArea;
    local playerList = game.Players:GetChildren; --It keeps saying function arguments expected near ":"
    local playerToTeleport = nil;

    for key, value in pairs(playerList) do
        playerToTeleport = game.Workspace:FindFirstChild(value.Name);
        if playerToTeleport ~= nill then
            player.Torso.CFrame = CFrame.new(spawnArea.Position);
        end
    end
end

script.Parent.MouseButton1Down:connect(onClicked)

Please Help
