help me with high score table script?

[shedokan]

can you tell me what's wrong with this php script?
here is the script:

<?php

$winscore = (int)$winscore;

// Create a Blank File if it doesn't already exist
if (!file_exists($filename))
{
$file=fopen($filename, "w");
fclose ($file);
}

// Read the file in
$oscores = file ($filename);
$numreadin = count($oscores);

// Break out the data into a new 2-d array called $tscores
for ($i = 0; $i < $numreadin; $i++)
{
$g = unserialize($oscores[$i]);
$tscores[$i][0] = $g[0];
$tscores[$i][1] = $g[1];
}

// Fill in any missing data with none/0
for ($i = $numreadin; $i < $scoresize; $i++)
{
$tscores[$i][0] = 0;
$tscores[$i][1] = "none";
}

// Process the actions 

// Insert a score/name
if ($action == "INSERT")
{

// Add name to end of list, and sort
$tscores[$scoresize + 1][0] = $winscore;
$tscores[$scoresize + 1][1] = $winname;
rsort ($tscores);

$file=fopen($filename, "w");

// Write them out
for ($i = 0; $i < $scoresize; $i++)
{
$st = serialize($tscores[$i]) . "\n";
fputs($file, $st);
}

fclose($file);
}

// Clear the list 
if ($action == "CLEAR")
{

$k[0] = 0;
$k[1] = "none";
$ser = serialize($k);

$file=fopen($filename, "w");

for ($i = 0; $i < $scoresize; $i++)
{
$st = $ser . "\n";
fputs($file, $st);
}

fclose($file);
}

// Process the OUTPUT options
if ($viewtype == "HTML")
{
// HTML PAGE CREATED HERE
?>


<table cellpadding=2 cellspacing=2 border=0 width="152">
<tr align=center> 
<th bgcolor="#000033"><font color="#FFFFFF" face="Arial, Helvetica, sans-serif">#</font></th>
<th bgcolor="#000033"><font color="#FFFFFF" face="Arial, Helvetica, sans-serif">Name</font></th>
<th bgcolor="#000033"><font color="#FFFFFF" face="Arial, Helvetica, sans-serif">Score</font></th>
</tr>

<?

for ($i = 0; $i < $scoresize; $i++)
{
echo ("<tr bgcolor='#666666' align='center'><td><font size='2' face='Arial, Helvetica, sans-serif'>");
echo ($i + 1);
echo ("</font></td><td><font size='2' face='Arial, Helvetica, sans-serif'>");
echo ($tscores[$i][1]);
echo ("</font></td><td><font size='2' face='Arial, Helvetica, sans-serif'>");
echo ($tscores[$i][0]);
echo ("</font></td></tr>");
}

?>
</table>
<?

}

// FLASH DATA CREATED HERE
if ($viewtype == "FLASH")
{
for ($i = 0; $i < $scoresize; $i++)
{
echo ("NAME" . $i . "=");
echo ($tscores[$i][1]);
echo ("&SCORE" . $i . "=");
echo ($tscores[$i][0]);
echo ("&");
}
}

?>
