[SOLVED] Further IF ELSE help

Hi all,

I have confused myself and would like another pair of eyes to look over this:

<?php
session_start()
?>

<body>
<div id="wrap">

<!-- content-wrap starts here -->
    
<div id="content-wrap">

	<div id="main">

        	username = "' . mysql_real_escape_string($_SESSION['username'], $conn) . '"';
		$result = mysql_query($query, $conn) or die(mysql_error($conn));

		$row = mysql_fetch_array($result);
		extract($row);
		mysql_free_result($result);

			if ($credits <> 0) 
				{
		?>

Ok there are 3 scenarios

1, User is logged in and has more than 0 Credits = Displays Form - Works

2, User is not logged in - Displays login message - Half works - Displays login message & Oops picture

3, User is logged in but has no credits - Display Oops Picture - Does not work - Displays Nothing

i have if'd and else'd myself to crazyness and I can no longer logically work it out! Anyone give me a hand?

 if ($credits <> 0)

Should be:

  if ($credits != 0)

or:

  if ($credits > 0)

The '<>' not-equal-to syntax is for MySQL, rather than PHP

After a lot more trying, finally got it working!
