Iam trying to execute a stored procedure from my php code........

My code is

$stmt=odbc_prepare($conn,'CALL Myprocedure(?,?,?)');
$a = "a";
$b = "b";
$c = "c";

$success = odbc_execute($stmt,array($a, $b, $c));



But it will result in an error

"SQL error: [Microsoft][ODBC SQL Server Driver]COUNT field incorrect or syntax error, SQL state 07001 in SQLExecute "


Any one pls help...........
