winset(world, null, "default.label2.text='[length(players)]'")
Problem description:
The game is supposed to calculate the length of the players on a player's login and winset a certain label's text to such. I am pretty sure that the window ID and the label ID are right.
Yet it remains the same.
Try this. Also, you'll need to set everyone else in the world as an update. Check the skin reference if you get confused.
