well i have the code

$(document).ready(function () {
var num_images = $('#numimages', window.opener.document).val();
var now_images = {NUMIMAGES};
var image_cost = {IMAGE_COST};
if (num_images != now_images) {
	var fee_diff = (now_images - num_images) * image_cost;
	$("#to_pay", window.opener.document).text(parseFloat($("#to_pay", window.opener.document).text()) + fee_diff);
	$('#numimages', window.opener.document).val(now_images);
}
});

but it doest seem to work just makes the window crash the full javascript on the page is

<script type="text/javascript" src="js/jquery.js"></script>
<script type="text/javascript">
$(document).ready(function () {
var num_images = $('#numimages', window.opener.document).val();
var now_images = {NUMIMAGES};
var image_cost = {IMAGE_COST};
if (num_images != now_images) {
	var fee_diff = (now_images - num_images) * image_cost;
	$("#to_pay", window.opener.document).text(parseFloat($("#to_pay", window.opener.document).text()) + fee_diff);
	$('#numimages', window.opener.document).val(now_images);
}
});
</script>
<!-- IF B_CROPSCREEN -->
<script type="text/javascript" src="js/jquery.imgareaselect.js"></script>
<script type="text/javascript">
function preview(img, selection) {
var scaleX = {SCALEX} / selection.width;
var scaleY = {SCALEY} / selection.height;

$('#thumbprev').css({
	width: Math.round((scaleX / {IMGRATIO}) * {IMGWIDTH}) + 'px',
	height: Math.round((scaleY / {IMGRATIO}) * {IMGHEIGHT}) + 'px',
	marginLeft: '-' + Math.round(scaleX * selection.x1) + 'px',
	marginTop: '-' + Math.round(scaleY * selection.y1) + 'px'
});
$('#x1').val(selection.x1 * {IMGRATIO});
$('#y1').val(selection.y1 * {IMGRATIO});
$('#x2').val(selection.x2 * {IMGRATIO});
$('#y2').val(selection.y2 * {IMGRATIO});
$('#w').val(selection.width * {IMGRATIO});
$('#h').val(selection.height * {IMGRATIO});
}

$(document).ready(function () {
$('#save_thumb').click(function() {
	var x1 = $('#x1').val();
	var y1 = $('#y1').val();
	var x2 = $('#x2').val();
	var y2 = $('#y2').val();
	var w = $('#w').val();
	var h = $('#h').val();
	if (x1=="" || y1=="" || x2=="" || y2=="" || w=="" || h=="") {
		alert("You must make a selection first");
		return false;
	} else {
		return true;
	}
});
});

$(window).load(function () {
$('#thumbnail').imgAreaSelect({ aspectRatio: '{RATIO}', onSelectChange: preview, x1: 0, y1: 0, x2: {STARTX}, y2: {STARTY} });
});

</script>

 

if thats of any help and the {NUMIMAGES} are variables that a phrased in by php when the page is loaded

I don't think jquery has any popup window functions (I use it all the time and have never seen anything) so you are probably best just using pure javascript for your popup functions.
