Hi can anyone help me....

I'm having trouble with the FBIK tool in maya....

I was hoping to get the same movement as the FBIK example that can be found in Maya, specifically the foot roll....the example has a great working foot roll, by just moving the effector.

I tried renaming all my joints so that its the same with the FBIK example of Maya...but i can't seem to get the same controls in the feet area....I want to get the same foot roll as the example has...

What can i do?
