Restricting Content to Members Only

In my sidebar I have a Alert News for MEMBERS ONLY.

So in my sidebar I have

<!--sidebar-->
[wp-members status="in"]

				<div id="sidebar">
			<div class="recentNews">
<marquee id="marqueeS" class="marqueeScroll" scrollamount="1" align="top" direction="up" height="100%" onmouseover="this.stop();" onmouseout="this.start();" loop="100">
				<?php
while($row = mysql_fetch_array($alertResults)){
echo"
				<p>".$row['alert_content']."<br></p>
";
}
?>
			</marquee>[/wp-members]

But it doesnt work. Do I maybe need to put it around the text, or does it work in pages.. or? What would be causing this problem
