problema con database

[techno]

ciao a tutti non capisco dove sta il problema:

switch($action){
    case "magazine" :
    $sql="form magazine Where Categoria='$cat'";
    $title=menu($cat);
    break;
    case "news" :
    $sql="from news";
    $title="Archivio news";
    break;
    case "search" :
    $sql="from magazine Where Article Like '%$cerca%' or Description Like '%$cerca%'";
    $title="Ricerca per $cerca";
    break;
}
mysql_select_db($db1,$dbconn) or die (mysql_error()." errore connessione db1"); 

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'magazine Where Categoria='CAT11'' at line 1 errore conteggio articoli 1
