First Make sure you can pump the ramp relatively good, Now take a look at how people go up a ramp, their shoulder are parallel to the board at all times no leaning back no leaning forward, this is also how you should stay when doing allies or else you will land and fall on your face or on your ass, got it? ok now the Ollie. Its the same as a flat ground Ollie except your landing is a little harder, the higher your Ollie is the harder it is to land so roll up with a little speed on the ramp right before you start to go back down pop a tiny Ollie, don't put your front feet to far back on the bolts just a little Ollie.  Try to slap down the board to the ramp and try to land evenly balanced on the board. Now if you have that down try it on large quarter pipes and try Olliing up from the transition to the vert try bigger Ollies (just op harder, don't pull your front foot back more that wont work..  Now try it with little grabs and stuff.
