Hi, i'm using the mysql function mysql_affected_rows. The script that doesn't works is this:

<?
     $result=mysql_query("UPDATE eic_labsexresumen SET grubtab='$grubtab[$i]',grubcal='$grubcal[$i]',grubtab2='$grubtab2[$i]',grubcal2='$grubcal2[$i]' WHERE idresures=$idresures AND labaleexc=$lab[$i]");
     $num=mysql_affected_rows($result);
     if($num==0):
      mysql_query("INSERT INTO eic_labsexresumen VALUES(0,NOW(),$idresures,$lab[$i],'0','$grubtab[$i]','$grubcal[$i]','$grubtab2[$i]','$grubcal2[$i]')");
     endif;
?>

The mysql_affected_rows always returns me 0.

What I'm doing wrong?
