I have some code that looks like this:<br />

<pre><code id="code-10-29103451-1">	$work = $_SESSION['Add_Name_1'].$_SESSION['Add_Name_2'].$_SESSION['Add_Name_3'];
	echo &quot;work = &quot;.$work;
	if ($work == &quot;NNN&quot;)
	{
		Header (&quot;Location:Update_Space.php&quot;);
		exit;
	}</code></pre>
I've checked the vars, if one is checked it works. &nbsp;But if none of the vars are checked , I get the following error:<br />
<br />
work = NNN<br />
Warning: Cannot modify header information - headers already sent by (output started at /home/langsyst/public_html<wbr />/seabreeze<wbr />software/R<wbr />etail/Spac<wbr />e_Contact_<wbr />Update.php<wbr />:27) in /home/langsyst/public_html<wbr />/seabreeze<wbr />software/R<wbr />etail/Spac<wbr />e_Contact_<wbr />Update.php<wbr /> on line 144<br />

Let me know if you need more info.
