What am I doing wrong?

I can't seem to understand PHP error trapping...I have it turned on in php.ini, and on the page in question, I have "error_reporting(E_ALL);" on the page in question below - the following code does NOT generate any errors, but it doesn't perform the insert either....the stored procedure exists, but even if I purposely misspell the stored procedure name, no errors are raised...any advice? <?php error_reporting(E_ALL); //submit the request //write entry into database $fname = $_POST[fname]; $lname = $_POST[lname]; $dept = $_POST[dept]; $phone = $_POST[phone]; $super = $_POST[super]; $groups = $_POST[groups]; //Assign the server connection to a variable $connect = mssql_connect('SERVERNAME,1433', 'username', 'password'); //Select your database and reference the connection mssql_select_db('DBName', $connect); // Create a new stored prodecure $stmt = mssql_init('sp_name'); // Bind the field names mssql_bind($stmt, '@fname',$fname,SQLVARCHAR,false,false,25); mssql_bind($stmt, '@lname',$lname,SQLVARCHAR,false,false,25); mssql_bind($stmt, '@dept',$dept,SQLVARCHAR,false,false,50); mssql_bind($stmt, '@phone',$phone,SQLVARCHAR,false,false,25); mssql_bind($stmt, '@super',$super,SQLVARCHAR,false,false,50); mssql_bind($stmt, '@groups',$groups,SQLVARCHAR,false,false,8000); // Execute mssql_execute($stmt); header("Location: done.php"); exit; ?>
