Falling Character needs its position reset after swipe

Hello! I've found a few scripts which I've copied/pasted/edited and was able to get my test level almost working: a character (which has this script attached to it) is falling. After the player swipes/moves the character in a direction and let's go, I need it to snap back X and Z positions, but not Y. I'm also having an issue just getting unity remote to work with android, so I added a "keypress" command which doesn't register at all. Any help would be appreciated:

 private var h : float;
 private var v : float;
 var horozontalSpeed : float = 1.0;
 var verticalSpeed : float = 1.0;
 
 //snap position on y axis
 
 var keepY : float;
 var keepX : float;
 var keepZ : float;
 
 function Start(){    
 
 }
  
 function Update()
 {
     keepY = transform.position.y;
     keepZ = 3.370361;
     keepX = -7.483171;
     
     }
     
      if(Input.GetKeyUp("a")){
             transform.Translate(keepX, keepY, keepZ, Space.World);
             Debug.Log("movingme");
             }
 
     if (Input.touchCount == 1)
     {
         var touch : Touch = Input.GetTouch(0);
  
       if (touch.phase == TouchPhase.Moved)
         {
             h = horozontalSpeed * touch.deltaPosition.x ;
             transform.Translate( 0, -h, 0, Space.World );
  
             v = verticalSpeed * touch.deltaPosition.y ;
             transform.Translate( v, 0, 0, Space.World );
         }
        if(touch.phase == TouchPhase.Ended){
                transform.Translate(keepX, keepY, keepZ, Space.World);
             }
             
        
     }
 
 function OnGUI () {
 
 GUI.Label (Rect (60,35,100,100), "hoziontal" + h, "box");
 GUI.Label (Rect (60,50,100,100), "hspeed" + horozontalSpeed, "box");
 GUI.Label (Rect (60,75,100,100), "vspeed" + verticalSpeed, "box");
