Drag multiple actors at once.

I have a game I'm working on that requires getting a bouncing ball into a goal by rotating platforms to the correct angles. I currently have it set up to where these platforms can rotate by dragging them to the right angle with a touch, however when I'm rotating one platform and then simultaneously use another finger and try to rotate another platform it doesn't register. Thank you in advance.

As far as providing help on your issue is concerned. You were getting help on the other thread and the fact that you were unable to understand the help makes me wonder if you have bitten off more than you can chew right now. When I first started using GS two years ago understanding the joystick demo and multitouch in general would have been way over my head. So If the other help you got was over your head I'm not sure how to help you. But I'll try (so I can make-up for my earlier assiness).
Here's the main idea. Create 5 actors that are 2x2 in size. Name them touch1, touch2, etc. They can all be unmovable.
Look at the joystick demo and copy those rules into each one. It will basically be
When mouse is down
constrain self.position x to game.touch1.x*
constrain self.position y to game.touch1.y*
OTHERWISE
change self.positionX to 0
change self.positionY to 0
(*For touch2 use game.touch2.x and game.touch2.y)
Then in the actors that you want to control you need an integer attribute (self.touchnumber)
Rule: When overlaps with actor touch1
change self.touchnumber to 1
OTHERWISE
change self.touchnumber to 0
Rule: When overlaps with actor touch2
change self.touchnumber to 2
OTHERWISE
change self.touchnumber to 0
(repeat this for all 5 touch actor overlaps)
Then this set of rules:
when self.touchnumeber = 1
constrain self.position x to game.touch1.x
constrain self.position y to game.touchy.x
when self.touchnumeber = 2
constrain self.position x to game.touch2.x
constrain self.position y to game.touch2.y
etc.
Again this is basically how the joystick demo works. the difference is that the joystick demo also uses some math to constrain the joystick to a circular area where you allow the player to drag the actors around anywhere on the screen.
Hope this helps.
