Siden bliver tom. Hvorfor?

Jeg har fundet en chat jeg skal have sat op. Når jeg logger ind bliver der refereret til en loginok.php. Siden er bare helt blank når jeg er logget ind. Den ser således ud:

<?





$time=time();

$select_chatten = mysql_query("SELECT id FROM users WHERE(username='chatten')");

$row_chatten = mysql_fetch_array($select_chatten);



$select_chattere = mysql_query("SELECT id,username,rum,answer FROM users WHERE(rum!=0)");

while($row_chattere=mysql_fetch_array($select_chattere)) {

if ($time-$row_chattere[answer] > 180)

{

mysql_query("INSERT INTO chat (rum,text,time,f,t) VALUES('$row_chattere[rum]','$row_chattere[username] blev smidt ud på grund af inaktivitet.','$time','$row_chatten[id]','0')");

mysql_query("UPDATE users SET rum='0',onlinechat='0' WHERE(id='$row_chattere[id]')");

}

}



if (!$id) {

$kryppassword=md5($password);

$select_logincheck = mysql_query("SELECT id,kryppassword,room FROM users WHERE(username='$username')");

$row_logincheck = mysql_fetch_array($select_logincheck);

if ($kryppassword!=$row_logincheck[kryppassword]) {

include("inc/header.php");

print "Forkert brugernavn eller password!";

include("inc/footer.php");

exit;

} else {

if ($login) {

$id=$row_logincheck[id];

session_register(id);

session_register(kryppassword);

$valign="middle";

mysql_query("UPDATE users SET logins=logins+1 WHERE(id='$id')");

include("inc/header.php");

print "<font size=\"4\"><b><center>Indlæser Brugerprofil...";

include("inc/footer.php");

flush();

print "

<meta http-equiv=\"refresh\" content=\"0;url=loginok.php\">

";

exit;

}

}

}

include("inc/password.php");



$select_info = mysql_query("SELECT username,onlinetid,spir,room,fisk FROM users WHERE(id='$id')");

$row_info = mysql_fetch_array($select_info);



$select_post = mysql_query("SELECT id FROM post WHERE(modtager='$id' && status='0')");



$select_online_users = mysql_query("SELECT id FROM users WHERE(rum!='0')");



$hour = floor($row_info[onlinetid]/60/60);

$tempmin =  $row_info[onlinetid]/60;

$min = floor($tempmin-$hour*60);



if(mysql_num_rows($select_post)>0) {

$read = "<img src=\"gfx/post/letter3.gif\" border=\"0\">";

}





echo "<font size=\"4\"><u>Yo ".$row_info['username']."</u></font><br><left><font size=\"2\">";

echo "<a href=\"#\" onclick=\"window.open('chat/index.php','looooooool','width=700,height=415,resizable=0,scrollbars=1');\">Chatten</a>";

echo "</font></center></font></center>";



echo "<b>Coinz: </b>".floor($row_info['spir'])."<br>";

echo "<b>Online Tid: </b>$hour timer og $min minutter<br>";

echo "<b>Online: </b>".mysql_num_rows($select_online_users)."<br>";

if ($row_info[room] != "0")

{

print "<b>Dit lejligheds Nummer er:</b> ".$row_info['room']."<br>";

}

print "<br>";

?>

  <?



print "<center><b><font size=3><font color=\"FFDE00\"></font></font></b><br><b><br>";

for($i=0; $row_info[fisk]>$i; $i++) {
