Paging problem please help

I'm trying to fix my paging problem, it works perfectly listing everything from pages 1-9. Once it hits page 10 and higher it gives me this error

Warning: Cannot modify header information - headers already sent by (output started at /home/layoutst/public_html/Graphics/graphics_header.php:7) in /home/layoutst/public_html/Graphics/category.php on line 27


echo '</div><span class="pagelinks">';
?>
<p>Page(s): 
<?php if ( $page > 1 )
{
	echo '<a href="/Graphics/'.$category['parentPerm'].'-'.$category['categoryPerm'].'-page'. ( $page - 1 ) .'.html">Previous</a> - ';
}
for ( $i = 1; $i <= $totalPages; $i++ )
{
	if ( $page == $i )
	{
		echo ' <strong>'.$i.'</strong> ';
	}
	else
	{
		echo ' <a href="/Graphics/'.$category['parentPerm'].'-'.$category['categoryPerm'].'-page'. $i .'.html">'.$i.'</a> ';
	}
}
if ( $page < $totalPages )
{
	echo ' - <a href="/Graphics/'.$category['parentPerm'].'-'.$category['categoryPerm'].'-page'. ( $page + 1 ) .'.html">Next</a></span>';
}?>
</p>

This is the paging code. Do you guys/girls see anything wrong with it?

You need to look at the graphics_header.php file to see what it is doing at line 7 to generate output, and if that output is desired, then check what is going on in category.php at line 27 that would need to set a HTTP header. If that is also doing what you want, then you need to either re-think the code logic/flow so that no output is generated before that command that sets a header, or else implement output buffering (with the additional overhead which that entails).

Do you think this would mess up the code it's line 20-29

$fetch = mysql_query ( "SELECT * FROM categories LEFT JOIN parents ON ( categoryParentID = parentID ) WHERE categoryPerm = '".$category."' LIMIT 1" );
if ( mysql_num_rows ( $fetch ) == 1 )
{
	$category = mysql_fetch_assoc ( $fetch );
}
else
{
	header ( "Location: /Graphics/" );
	exit();
}

sorry i just cant see how it would give me a error. on line 7 it's nothing but html so i know that cant be it.

"nothing but html" is, in fact, output. Thus when you get to the else condition in your last post and try to execute the header() command, it fails, because you've already sent headers (they get sent as soon as any kind of output is sent to the client).
