How do I do an Advanced Flip Trick in Nail the trick mode on Tony Hawks Proving Ground?

Question

I know how to do a flip trick in nail the trick mode, but whats the difference between that and an advanced flip trick?

Answer 1

All you need to do is enter Nail the Grab mode, do a finger flip. When the finger flip goes all the way around, do another one right away without letting go of the L2 button. (Or whatever it is on the 360). This took me forever to figure out, and I ended up doing it on accident.
