An array reference is actually a pointer(as we would have said in C++) that points to the starting memoery location of the array?! And de-reference means to point to the value of memory location instead of the memory location itself?

Also this:

my @titlelist;
open FILE, "<$ENV{'DOCUMENT_ROOT'}/data/vault/titlelist.txt" or die
$!;
     @titlelist = <FILE>;
close FILE;

print br() x 3;
print start_form( action=>'/cgi-bin/admin.pl' );
  print table( {class=>'user_form'},
     Tr( td(  '&#928;&#941;&#962; &#956;&#959;&#965; &#964;&#953; &#95
+2;&#945; &#942;&#952;&#949;&#955;&#949;&#962;:'                   ),
td( popup_menu( -name=>'title' -values=>\@titlelist ))),
     Tr( td(  '&#922;&#940;&#964;&#953; &#940;&#955;&#955;&#959; &#960
+;&#959;&#965; &#952;&#945; &#942;&#952;&#949;&#955;&#949;&#962; &#957
+;&#945; &#963;&#967;&#959;&#955;&#953;&#940;&#963;&#949;&#953;&#962;?
+'  ),
td( textarea( -name=>'remark', -rows=>4, -columns=>25 ))),
     Tr( td(  '&#932;&#959; &#964;&#951;&#955;&#941;&#966;&#969;&#957;
+&#959; &#949;&#960;&#953;&#954;&#959;&#953;&#957;&#969;&#957;&#943;&#
+945;&#962; &#963;&#959;&#965; &#947;&#953;&#945; &#949;&#960;&#953;&#
+946;&#949;&#946;&#945;&#943;&#969;&#963;&#951;
&#949;&#943;&#957;&#945;&#953;:'  ),  td( textfield( -name=>'phone' ))
+),

     Tr( td(  a( {href=>'/cgi-bin/show.pl?name=showbook'},
font( {size=>3, color=>'yellow'},  '&#917;&#956;&#966;&#940;&#957;&#95
+3;&#963;&#951;!' ))),
         td(  submit( '&#913;&#960;&#959;&#963;&#964;&#959;&#955;&#942
+;!' )))
  );

      print hidden(-name=>'date',  -value=>$date);
      print hidden(-name=>'host',  -value=>$host);
print end_form();

Although @titlelist is filled with all entries from titlelist.txt file(one entry per line), when it gets printed with popup_menu it displays nothing at all!!

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
