Hi guys,
i was reading the Body Language Advanced 3d Character Rigging book http://www.amazon.com/Body-Language-Advanced-Character-Rigging/dp/0470173874/ref=sr_1_1?ie=UTF8&qid=1314993282&sr=8-1
And i was following the book when i got to the arm rigging part. It has a forearm bone rig idea but the explanation is really weird to the point i couldn’t follow. The writter starts applying multiple constraints to the same object (which maya won’t let me) and by the end the actual controller has nothing linked to it, so it doesn’t controll a thing.
If anyone has read this book and was willing to help me i’d be happy 
thanks in advance
