hi all, i keep getting this parse error

Code:
Parse error: parse error in /www/bostoncreative/session1.php on line 1
evertime i try to run this piece of code:

Code:
<?php
session_start();

if (!$phpsessid) {

session_register('font_family');
session_register('font_size');

} else if ((!$font_family) || ($font_size)) {

session_register('font_family');
session_register('font_size');

}

if (!$font_family) {
	$font_family = "sans-serif";
}
if (!font_size) {
	$font_size = "10";
}

?>


<HTML>
<HEAD>


bla bla bla


</BODY>
</HTML>

i'm following an example from a book word by word, but i just don't understand why this particular script is getting a parse error.

the script is in the root directory. i'm able to run other php scritps from there but apparently not this one.

any clues ????
