I am coding a Marble Maze with accelerometer. Here is my code.
package {

public class MarbleMaze_sanJ01 extends MovieClip {
// Constantes
static const speed:Number = .3;
static const marbleSize:Number = 20;
static const holeDist:Number = 5;
static const mapRect:Rectangle = new Rectangle(2, 2, 1918, 1078);

I get the following error:
What am I doing wrong? Can you help me. Thank you in advance.
Error # 1010: A term is undefined and has no properties.
at MarbleMaze_sanJ01 / moveMarble ()
at MarbleMaze_sanJ01 / gameLoop ()
Best regard
