Issues with Functions

This code snippet, when called, displays a news alert on a page. However, when the News Alert is turned off (click here to turn off), the database field doesn't change, and thus, the code doesn't work.

function news_alert($m_alert_banner, $m_id){

	if($m_alert_banner == "Yes") {
		$news_alert = mysql_query("SELECT * FROM `TABLE`");
		while ($c = mysql_fetch_array($news_alert)) { 

	echo ("<center><div class=\"message loginerror\">$c[news_alert]<br/> <a href=\"?act=off\">Turn Off News Alert</a></center> <br/><center>");  }

	if ($_GET['act'] == "off") { echo("<div class=\"message success\">You've turned off the News Alert. $m_id</div>");
		mysql_query("UPDATE `TABLE` SET `alert_banner` = 'No' WHERE `id` = '$m_id'"); }
	}
return $news_alert_banner;
}

That is the function, and here is how I'm calling it.

news_alert("Yes", "$m_id");

Try calling it like:

news_alert("Yes", $m_id);

You only need to put quotes around a string, not the variable. Meaning remove the quote from the second parameter since you're passing it as a variable and not a string.
