Hi! Little problem there. Can someone tell me what's the problem with this? The first test below works while the second doesn't. I have to use strict so I need to know why it doesn't work and what I have to do to fix the problem in the second test. It complains when I put items in the second dimension of the array..."Can't use string ("group 0") as an ARRAY ref while "strict refs" in use at test.pl line 18." Thx a lot! Franck

#FIRST TEST
$i = 0;
$j = 0;

@data = ();

  for ($i=0; $i<=3; $i++){
    $data[$i] = "group $i";
    
        for ($j=0; $j<=3; $j++){
          $temp1 = $j+$i+10;
          $data[$i][$j] = "user $temp1";
          
            for ($k=0; $k<=3; $k++){
               $temp2 = $k+100;
               $data[$i][$j][$k] = " $temp2";
            }
         }
      }

  for ($i=0; $i<=3; $i++){  
    print "\n\n$data[$i] own: ";  
        for ($j=0; $j<=3; $j++){ 
          print "\n     $data[$i][$j] who have privilege ";
