ASP.NET/SQL Not retrieving correct value from database - asp.net

Question

So I'm trying to create a monopoly web game using asp.net. I was having issues with variables being saved due to the postback, so I've created a database which stores all the info about the players and squares etc. The problem I'm having now however is for some reason the current player ID isn't being stored/retrieved correctly. I apologise for the relatively long wall of code;

int currentPlayerID = 0;
int currentSquareID = 0;
int freeParkingAmount = 500;

As far as I know the database code I've got works fine as I can resume a game and it will set the player position to be the square they were at before. But for some reason when starting the game it is constantly player 2's turn, and the changeActivePlayer() doesn't seem do anything to help this. I stepped through the code line by line and after clicking the EndTurnButton the playerID had changed but when it came to getting the values from the database it was back to player 2's ID. I'm also not sure why it defaults to player 2, seeing as when I call the start game function I set the current player to players[0] so surely it should be player 1? Any help on this would be appreciated.
