php e doppio frame

Nel mio sito (www.fdiodato.tk) ho un guestbook. Se si accede, nella pagina del guestbook, sotto la scritta "guestbook", c`e` scritto "home". Se si preme, compaiono due frame con il menu! Non so come risolvere il problema.
Vi copio parte dello script del mio guestbook:

Codice PHP:

<? //--Change the following variables //Title of your guestbook $title = "Guestbook"; //Change "admin" with your own password. It's required when you delete an entry $admin_password = "xxxxxxx"; //Enter your email here $admin_email = "info@fdiodato.tk"; //Your website URL $home = "http://fdiodato.altervista.org/ita/indice.htm"; //Send you an email when someone add your guestbook, YES or NO $notify = "YES"; //Your Operating System //For Windows/NT user : WIN //For Linux/Unix user : UNIX $os = "WIN"; //Maximum entry per page when you view your guestbook $max_entry_per_page = "10"; //Name of file used to store your entry, change it if necessary $data_file = "gbook.dat"; <html> <head><title>www.fdiodato.tk</title></head> <body bgcolor="<?=$background?>" link="<?=$link?>" vlink="<?=$visited_link?>" alink="<?=$active_link?>" topmargin="0" marginheight="0" style="font-family:<?=$font_face?>"> <center> <font size="6" color="<?=$title_color?>"><b><?=$title?></b></font><br> <font size="2" color="<?=$title_color?>">(:: <b><a href="<?=$home?>"><font color="<?=$title_color?>"> Home</font></a></b> ::)</font><br><br> <table width="600" cellpadding="0" cellspacing="1" border="0"> <tr bgcolor="<?=$table_border?>"> <td> <table width="100%" cellpadding="4" cellspacing="1" border="0"> <tr> <td bgcolor="<?=$table_top?>" colspan="2" width="585"> <font size="2" color="#ffffff"><b>Premi <a href="<?="$PHP_SELF?do=add_form&page=$page"?>">qui</a> per firmare il guestbook</font></b> </td> <td bgcolor="<?=$table_top?>" align="center" width="15"> <a href="mailto:<?=$admin_email?>"><img src="webmaster.gif" border="0" alt="Contatta il webmaster" align="center"></a> </td> </tr> <? $jml_page = intval($jmlrec/$max_entry_per_page); $sisa = $jmlrec%$max_entry_per_page; if ($sisa > 0) $jml_page++; $no = $page*$max_entry_per_page-$max_entry_per_page; if ($jmlrec == 0) echo "<tr><td colspan=\"3\" bgcolor=\"white\" align=\"center\"><font size=\"3\">Non ci sono ancora commenti.</font></td></tr>"; $w = 0; //--Color for ($i=0; $i<$max_entry_per_page; $i++) { $no++; $recno = $no-1; if (isset($record[$recno])) { $row = explode("|~|",$record[$recno]); if ($w==0) { $warna = $table_content_1a; $warna2 = $table_content_1b; $w=1; } else { $warna = $table_content_2a; $warna2 = $table_content_2b; $w=0; } echo "<tr> <td bgcolor=\"$warna2\" align=\"center\" valign=\"top\" width=\"15\"> <font size=\"2\">$no</font> </td> <td bgcolor=\"$warna\" width=\"570\"> <table border=\"0\" width=\"100%\"> <tr> <td> <font size=\"1\">$row[2]</font><br> <font size=\"2\"><b>$row[3]</b></font> </td> "; echo "<td align=right valign=top> <a href=\"mailto:$row[4]\"><img src=\"email.gif\" border=0 alt=\"$row[3]'s email\"></a>"; if (trim($row[6]) <> "" && trim($row[6]) <> "http://") { if (ereg("^http://", trim($row[6]))) echo " <a href=\"$row[6]\" TARGET=\"_blank\"><img src=\"homepage.gif\" border=\"0\" alt=\"$row[3]'s homepage\"></a>"; else echo " <a href=\"http://$row[6]\" TARGET=\"_blank\"><img src=\"homepage.gif\" border=\"0\" alt=\"$row[3]'s homepage\"></a>"; } echo "</td></tr></table>"; echo "<br><table border=\"0\" width=\"100%\"> <tr><td width=\"5\"> </td><td> <font size=\"2\" face=\"$message_font_face\" size=\"$message_font_size\">$row[5]</font> </td></tr> </table> "; echo "</td>"; echo "<td valign=\"top\" bgcolor=\"$warna2\" align=\"center\" width=\"15\"> <a href=\"$PHP_SELF?do=del&id=$row[1]&page=$page\"> <img src=\"del.gif\" alt=\"Delete entry # $no\" border=0 align=\"center\"></a> </td> </tr>"; } //--end if } //--end for echo "<tr><td colspan=\"3\" bgcolor=\"$table_bottom\" align=\"center\" width=\"600\"><font size=\"1\">"; if ($jml_page > 1) { if ($page <> 1) echo "[<a href=\"$PHP_SELF?page=1\">Top</a>] "; else echo "[Top] "; echo "Page # "; if ($jml_page > 10) { if ($page < 5) { $start = 1; $stop = 10; } elseif ($jml_page - $page < 5) { $start = $jml_page - 9; $stop = $jml_page; } else { $start = $page-4; $stop = $page+5; } if ($start <> 1) echo "...
