tæller +1

Hvorfor vil den ikke +1 i hits i tabellen når det er popup?

Script 1 vil den ikke tælle, men det vil den godt i script 2

Script 1

<center><TABLE WIDTH="370" BORDER="0" CELLSPACING="0" bgcolor="white">
<TR VALIGN="center">
<?php
$i = 0;
$antal = 5;
if(isset($_GET['id'])) {
  mysql_query("UPDATE farvebilleder SET hits = hits + 1 WHERE id = $id");
} else {
$sql = mysql_query("SELECT * FROM farvebilleder ORDER BY hits desc") or die(mysql_error());
while ($row = mysql_fetch_array($sql))
{
  $i++;
  echo "<td><a onClick=\"window.open('$row[link]','win1','height=310,width=400');\" style=\"cursor:hand\" onFocus=\"blur()\"><IMG SRC=\"$row[pic]\" width=\"96\" height=\"65\" BORDER=\"0\" ALT=\"$row[navn]\"></a></td>";
  if ($i % $antal == 0)
  {
    echo "</tr><tr>";
  }
}
?>
</TR>
</TABLE></center>
<?
}
?>

Script 2

<center><TABLE WIDTH="370" BORDER="0" CELLSPACING="0" bgcolor="white">
<TR VALIGN=\"center\">
<?php
$i = 0;
$antal = 5;
if(isset($_GET['id'])) {
  mysql_query("UPDATE farvebilleder SET hits = hits + 1 WHERE id = $id");
} else {
$sql = mysql_query("SELECT * FROM farvebilleder ORDER BY 'kategori'");
while ($row = mysql_fetch_array($sql))
{
  $i++;
  echo "<td><a href=\"".$_SERVER['PHP_SELF']."?id=$row[id]&link=$row[link]\" onFocus=\"blur()\"><IMG SRC=\"$row[pic]\" width=\"96\" height=\"65\" BORDER=\"0\" ALT=\"$row[navn]\"></a></td>";
  if ($i % $antal == 0)
