Show us the code you're using so far.

this is the part that i join an array together

my $att_name = join '<br>',@att_name;

i guess this is the important part

does it help or do you want more?

Single quotes will cause a that string to be interpreted literally. That means that when you use '\n', you literally mean a backslash character followed by the letter 'n'. If you wanted \n to be a newline character, you'd need to change the single quotes to double ones. I suspect that's your problem.

sorry - i misunderstood your question

this takes it a bit further - and sorts out your problem

[b]#!/usr/bin/perl[/b]

print "Content-type: text/html\n\n";

read (STDIN, $buffer, $ENV{'CONTENT_LENGTH'});

if ($buffer) {

  print "We have POST data...<br>";
  print $buffer;
  
  $buffer =~ s/^editfield=//;
  
  $buffer =~ s/%0D%0A/\n/g;
  
  open (OUT, "> user_editable.txt");
  print OUT $buffer;
  close OUT;
  
}

open (IN, "< user_editable.txt");
undef $/;
$_ = <IN>;
$/ = "\n";
close IN;

print <<HTML;
<form action=$0 method=POST>
  <textarea cols=50 rows=10 name=editfield>$_</textarea>
  <input type=submit>
</form>
HTML
# end of script
