Selection From Database Is Incorrect

I have over 50 rows in this table and my bizIDNum is always getting set to 4. Please take a look at the code and tell me whats wrong. If I do the select statement in the database the return number is correct. here is the code

 

// db connection

SqlConnection sqlConnection = new SqlConnection(ConfigurationManager.ConnectionStrings["work4tipsConnectionString"].ConnectionString);

sqlConnection.Open();

string sqlSelect = "SELECT MAX(bizID) FROM business";

SqlCommand sqlCommand = new SqlCommand(sqlSelect, sqlConnection);

//sqlCommand.Parameters.Add("@Username", SqlDbType.VarChar).Value = username;

string bizIdNum = (string)sqlCommand.ExecuteScalar();

sqlConnection.Close();

sqlConnection.Dispose();
