Simple Session Problem [RESOLVED]

[modernthinker]

I am passing my session variable from one page to another then storing the value into my database, for some reason my code isn't working?

page one:

Session["userID"] = "4545";
Server.Transfer("CreateProfile.aspx");

page two:

SQL = "INSERT INTO LoginDetails (UserID, Username, [Password])"+
					"VALUES (@UserID, @Username, @Password)";

				OleDbCommand WO_Cmd2 = new OleDbCommand(SQL, WO_Conn);

				WO_Cmd2.Parameters.Add("@UserID", Session["userID"]);
				WO_Cmd2.Parameters.Add("@Username", txtUsername.Text);
				WO_Cmd2.Parameters.Add("@Password", txtPassword.Text);
					
				WO_Conn.Open();
				WO_Cmd2.ExecuteNonQuery();
				WO_Conn.Close();

				Server.Transfer("Login.aspx");

Error:

System.Data.OleDb.OleDbException: Parameter @UserID has no default value.

Anyone know what i am doing wrong?
