Help with ps3 controller and motion joy

[Vallina]

I am trying to assign the buttons on my ps3 controller. I am using motion joy. When i click to assign button, and I hit the button on my controller. It does not work. This is quite annoying. Can someone please help me? I can make a profile in motion joy and use all keypad options like make the X button K, ect. The only issue with this is the axis joystick. I can't assign it on an access. I've seen pictures of it done on here y+ axis, y-, x+,x-. How can I get this to work? It seems to be a problem with JPCSP not responding.
