So with my code below im really stumped on whats happening. I've looking on the internet and looked at a bunch of code and it seems to be similar to mine but i have no clue why mine isnt working. when you click on the next(or any page) link it just displays an empty page. it might be a really simple solution or just a dumb mistake on my part on the code but i just cant figure out whats happening.

<?php
    mysql_connect ("localhost", "root","root") or die (mysql_error());
    mysql_select_db ("FHSNL");
	
	//sets all values in form to php variables
    $surname = $_GET['surname'];
    $given = $_GET['given'];
	$maiden = $_GET['maiden'];
	$deathdate = $_GET['death'];
	$deathrange = $_GET['range'];
	$deathbefore = $_GET['death'] - $deathrange;
	$deathafter = $_GET['death'] + $deathrange;

	$birth = $_GET['birth'];
	$birthplace = $_GET['birthplace'];
	$deathplace = $_GET['deathplace'];
	$erected = $_GET['erected'];
	$region = $_GET['region'];
	$religion = $_GET['religion'];
	//divides into smaller sql pieces for filled in form input.
	if($surname)$piece[] .= "`SURNAME` LIKE '%$surname%'";

Thanks for the help

Where you have queries:

$sql_p = mysql_query("SELECT * FROM `HEADSTONESA` WHERE $sqlend $max") or die(mysql_error());

like this, echo them out to see what's being passed to MySQL server:

echo "SELECT * FROM `HEADSTONESA` WHERE $sqlend $max";

Check them in a MySQL GUI if they look OK, just to be sure. Also you could use the "title" attribute to check the number in your links before you press them, but that should show up in the address bar anyway - so perhaps less impt:

<a href='{$_SERVER['PHP_SELF']}?pn=$next' title='$next'>Next -></a>
