Trouble with WHERE clause (using PHP)

I have a database with three columns: ID, UniqueID, FileName. I am trying to extract the FileName based on the UniqueID and then print it to the screen. This is what I have:

ShowRandomPic();

function ShowRandomPic(){
	$con = mysql_connect("localhost", "DB_User", "Password");
	if (!$con)
  	{
  		die('Could not connect: ' . mysql_error());
 	}
	$DB = "DataBase";
	mysql_select_db($DB) or die(mysql_error());
	$result = mysql_query("SELECT * FROM table WHERE UniqueID = 'nCSoHUaDMz'");
	$row = mysql_fetch_assoc($result);
	$filename = $row['FileName'];
	echo $filename;
}

Code (markup):

When the page is loaded the screen is just blank.
I cannot for the life of me figure out what I am doing wrong. Any ideas?

Thanks a lot,
Pat

 

wow guys... sorry, I made a ridiculous mistake. My opening tag was "<PHP?" instead of "<?PHP"


Problem SOLVED.
