If it were me, I'd be doing it with jQuery.

Here's the full page (sorry about the inline post, I've forgotten the  
link to the web page to display code snippets)

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
	"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
	<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
	<script src="jquery.js" type="text/javascript" charset="utf-8"></ 
script>

	<title>checkboxes</title>
	<script type="text/javascript" charset="utf-8">
	$(function(){
		$(".aCheckbox").click(function(){
			if($(this).is(':checked')){
				alert("checkbox "+this.name + "\nHas a value of "+$(this).val());
				}
			});
		});
	</script>
</head>
<body>
	<form action="checkboxes.html" method="post" accept-charset="utf-8">
		<input type="checkbox" name="thisName" value="1" class =  
"aCheckbox"> Checkbox 1
		<input type="checkbox" name="thisName1" value="2" class =  
"aCheckbox"> Checkbox 2
		<input type="checkbox" name="thisName2" value="3" class =  
"aCheckbox"> Checkbox 3
		<input type="checkbox" name="thisName3" value="4" class =  
"aCheckbox"> Checkbox 4
	</form>
</body>
</html>

You can see this in action at <http:demo.customikesolutions.com/ 
checkboxes.html>

if you expand your list of checkboxes, you just need to give them a  
class of "aCheckbox" (or whatever you call it) and it will "just work".

Hope this helps.
