elasolova

I am trying to implement a simle guestbook system. I just have one php file and a log file to keep track of the comments. It is giving a parse error on line 84 that i could not figure out. Can you help me please? Here is the code

<html>
<head>
<title>GuestBook</title>
<style type = "text/css">
body{
	background: tan;
}
</style>
</head>
<body>
<center>
<h1>Sample Guestbook</h1>


<table border = 1
	width = 500>
<tr>
   <td colspan = 2> <center>
	<h3>Comments</h3>
   </td>
</tr>

<tr>

<?php
$userName=$_POST["userName"];
$content=$_POST["content"];

if($userName=="")
{

} else { 
 post();
}

showComments();



function post()
{
   global $commentFile;
   $commentFile = "comment.log";
   $fp = fopen($commentFile, "a");
$data="";
$data .= <<<HERE
$userName  . ":" . $content . "\n";
HERE; 
   fputs($fp, $data);
   fclose($fp);

}




function showComments() {
global $commentFile;

$commentFile = "comment.log";

$fp = fopen($commentFile, "r");
while(!feof($fp))
{
 $comments .= fgets($fp);
}
fclose($fp);
$comments = split("\n", $comments);




foreach($comments as $cur) {
list($user, $says) = explode(":",$cur);
print <<<HERE

   <td colspan=2>
	<font color="red">$user</font> says
	$says
   </td>
HERE;

}
}
?>
	<td><center>
	<form action="guest.php" method="post">
	Name <input type="text" name ="userName" value="">
	<textarea name="content" rows=20
				  cols=40>Enter your comment here!</textarea><br>
 	<input type="submit" value="Post"></form>
	</center></td>
</tr>

</center>
</body>
