Why won't my code work? PHP.?

[christsealed]

For some reason, when I check this code, I get the following error.
Parse error: parse error, unexpected T_CONSTANT_ENCAPSED_STRING in fpi_upload.php on line 68

I've checked and apparently it's due to some basic syntax error, but I can't find it when I check. Help?

$db = mysql_connect($host,$dbuser,$dbpass) or die("error=could not connect to $host");
$db = mysql_select_db($dbname);
if(!$db)
{
print "error=could not connect to $dbname table";
exit;
}

BTW: Line 68 is this one:
