The part of the code that created the drop down menu is some lines below the code that i originally posted, here is is: 
print start_form( action=>'/cgi-bin/index.pl' );
    print h1( {class=>'lime'},  "Επέλεξ&
+#949; το κείμενο π&
+#959;υ σε ενδιαφέ&#
+961;ει => ",
                                popup_menu( -name=>'select', -values=>
+\@display_files ),
                                submit('ok'));
print end_form;

Also i have checked and verified that the returned string values coming back to index.pl when i user makes a valid item selection from the drop down menu is in 100% correct.

That means that each time i select something form the list i get a proper string value back that corresponds to an existing filename which is an item of @display_files

So we know for usre know the the param('select') holds a valid string value.
