text only and text sizer


$text_only = isset($_GET['text_only']) ? $_GET['text_only'] : 1;

if ($text_only==1) {
?>
<a href="<?php echo $_SERVER['PHP_SELF'];?>?text_only=0">off</a>
// import css here
<?
}
else {
?>
<a href="<?php echo $_SERVER['PHP_SELF'];?>?text_only=1">on</a></span>
// import css here
<?
}
?>


secondly the text size links


<a href="<? $_SERVER['PHP_SELF']; ?>?text_size=medium" class="size1"
id="one">A</a>
<a href="<? $_SERVER['PHP_SELF']; ?>?text_size=larger" class="size2"
id="two">A</a>
<a href="<? $_SERVER['PHP_SELF']; ?>?text_size=largest" class="size3"
id="three">A</a>


<?
$text_size = isset( $_REQUEST['text_size'] ) ? $_REQUEST['text_size'] : '';

switch ($text_size) {
case "medium":
?>
<link href="css/medium.css" rel="style***" type="text/css" />
<?
break;
case "larger":
?>
<link href="css/larger.css" rel="style***" type="text/css" />
<?
break;
case "largest":
?>
<link href="css/largest.css" rel="style***" type="text/css" />
<?
break;
}
?>

these work great independently but when I use one the other switches off.
any ideas how I can combine them?
