    Actually I would think it comes out to the same number of if's but in a more readable format where you can see immediately which elements had to be true to force that query, either way I would recommend building the query on the fly if that is at all possible. Either way this is 25 lines instead of 70ish.

    if ($1 && $2 && $3) { #a } if ($1 && $2) { #b } if ($1 && $3) { #c }

    versus

    if ($1) { if ($2) { if ($3) { #a } else { #b } } elsif ($3) { #c } }

    I got a little bored and tried it out. Unless i screwed something up I think you are messing several combinations.

    if ($name && $vorname && $plz && $tel && $tel49) { $qry = ""} elsif ($name && $vorname && $plz && $tel) { $qry = ""} elsif ($vorname && $plz && $tel && $tel49) { $qry = ""} elsif ($name && $plz && $tel && $tel49) { $qry = ""} elsif ($name && $vorname && $plz) { $qry = ""} elsif ($name && $plz && $tel) { $qry = ""} elsif ($name && $tel && $tel49) { $qry = ""} elsif ($vorname && $plz && $tel) { $qry = ""} elsif ($plz && $tel && $tel49) { $qry = ""} elsif ($name && $vorname) { $qry = ""} elsif ($name && $plz) { $qry = ""} elsif ($name && $tel) { $qry = ""} elsif ($name && $tel49) { $qry = ""} elsif ($vorname && $plz) { $qry = ""} elsif ($plz && $tel) { $qry = ""} elsif ($tel && $tel49) { $qry = ""} elsif ($plz) { $qry = ""} elsif ($name) { $qry = ""} elsif ($tel) { $qry = ""} elsif ($tel49) { $qry = ""} elsif ($vorname) { $qry = ""}

      and what is with the combination $vorname && tel && tel49 ;)
      i really like this idear of hash and a hash with all bitmasks
      kd ultibuzz

        Tha combination? Thats just all the combinations you where testing for in your old code. I agree bitmasks or building as you go are probably better solutions. Just giving you more than one way to do it.
