Hello, $0$0 $0 $0I have been following tutorials on how to create a 'Puzzle game' using Visual Studio 2010, to be used on a windows phone...$0 $0$0 $0 $0I have managed to get one puzzle to work, however I have encountered problems when trying to replicate the same code on other pages to create other puzzle games on the same application.$0 $0$0 $0 $0 $0$0 $0 $0

namespace WindowsPhonePuzzle

{

    public partial class PuzzlePage : PhoneApplicationPage

    {

        private const double DoubleTapSpeed = 500;

        private const int ImageSize = 435;

        private PuzzleGame game;

        private Canvas[] puzzlePieces;

        private Stream imageStream;

        private long lastTapTicks;

        private int movingPieceId = -1;

        private int movingPieceDirection;

        private double movingPieceStartingPosition;

        public Stream ImageStream

        {

$0 $0$0 $0 $0The errors seem to focus on this part of my code, I have simply copied and pasted the whole code over to another page, could it be that I have to rename each differently? $0 $0$0 $0 $0If anyone has any idea please help.$0
