Exclamation [AS3] walking on slope with real gravity

ok, well I scratched my old physics on the game and decided to go based on real physics...I used an actualy gravity algorithum based on mass, distance, yada yada...I'm still having a problem with walking on a slope, making the character go up and down basically.

ActionScript Code:
function charDist(event:Event):void             {                 gPull = gravity * eraserMass / dist * dist;                 getDist(eraserMan.x, eraserMan.y, theGround.x, theGround.y);                 trace(touchDown);             }             function getDist(x1:Number, y1:Number, x2:Number, y2:Number):Number             {                 dx = x1 - x2;                 dy = y1 - y2;                 dist = Math.sqrt(dx * dx + dy * dy);                 return dist;             }             function gravity(event:Event):void             {                 velocity -=  gPull;                 while (theGround.hitTestPoint(eraserMan.x,eraserMan.y,true))                 {                     eraserMan.y +=  velocity;                                     }                 while (! theGround.hitTestPoint(eraserMan.x,eraserMan.y,true))                 {                     eraserMan.y -=  velocity;                                     }             }

the gravity function is where the issue is...the character falls faster and slower based on weight and distance...thats all great. But once I hit the ground, he stays linear...help please

I got it now, I'm posting a zip with the fla and class files...it seems jumpy though, any ideas on smoothing it out?
