Issues with picking in c# XNA

Im attempting to make a chess game, to move the pieces im using picking, so the user clicks on a piece to set it as the selected piece, then on the square they want to move it to. This works the first time, but when you click on a different piece to make that the selected piece, and then an empty square to move it, it moves the first selected piece instead. Here's my code and thanks in advance to anyone who can help.

string[,] Board =      {          {"BRook1", "BKnight1", "BBisop1", "BQueen", "BKing", "BBishop2", "BKnight2", "BRook2"},          {"BPawn1", "BPawn2", "BPawn3", "BPawn4", "BPawn5", "BPawn6", "BPawn7", "BPawn8"},          {null, null, null, null, null, null, null, null },          {null, null, null, null, null, null, null, null },          {null, null, null, null, null, null, null, null },          {null, null, null, null, null, null, null, null },          {"WPawn1", "WPawn2", "WPawn3", "WPawn4", "WPawn5", "WPawn6", "WPawn7", "WPawn8"},          {"WRook1", "WKnight1", "WBishop1", "WQueen", "WKing", "WBishop2", "WKnight2", "WRook2"},      };            MouseState mouseState = Mouse.GetState();          decimal decMousex = mouseState.X;          decimal decMousey = mouseState.Y;          y = Convert.ToInt32(Math.Floor(decMousex / 75));          x = Convert.ToInt32(Math.Floor(decMousey / 75));                      if (mouseState.LeftButton == ButtonState.Pressed              && Board[x,y] != null && pieceSelected == null)          {              pieceSelected = Board[x, y];              selectedX = x;              selectedY = y;          }            else if (mouseState.LeftButton == ButtonState.Pressed                  && Board[x,y] == null && pieceSelected != null)          {              Board[selectedX, selectedY] = null;              Board[x, y] = pieceSelected;              pieceSelected = null;          }
