Pulley with Ropes

[RedMser]

So I did create ropes, and there is a basket attached to it laying on the floor with a brick on it. On the other side (using a pulley) there is a lantern hanging at the ceiling. I created it using 3 ropes... So when you take away the brick, the basket should get pulled up by the rope and the lantern should fall down because the lantern is more heavier than the basket. But how to do that? I have a script checking once the brick isn't laying on the basket anymore. All I need is to know how to make the rope pull up on the basket one (it seems very easy to make the lantern fall - using static physics)?

EDIT: Also I beleave this is the wrong category... Meh.
EDIT2: Yeah it should be in CS Development Support... I am really new to this forum, so don't blame me
