Ciao a tutti, sto provando ad avere da php un risultato di una storeprocedure

Codice PHP:
// Connect to SQL Server and check for errors$conn = mssql_connect($db_host,$db_user,$db_password);if ($conn===false){    echo '<p>Cannot connect to SQL Server Database. Please try again later.</p>';    exit;}if (mssql_select_db("miodatabase",$conn) === false) {    echo '<p>Cannot connect to MyDatabase. Please try again later.</p>';    exit;}$proc = mssql_init('mai_proc',$conn);
if ($result mssql_execute($proc)) {    if ($row mssql_fetch_row($result))     {        // now you can deal with the $row array to check out your results    }} 
ma ottengo sempre un errore


Warning: mssql_execute() [function.mssql-execute]: message: Incorrect syntax near ','. (severity 15) in /home/camicie/public_html/documenti/Pivot2.php on line 23
