Could someone please tell me how to get this code working on a webpage? Particularly what should go in the header?

Sorry if this is a basic question...steep learning curve!
Thanks
Your code is using the jQuery JavaScript library ... so your head will need to contain :
<script type="text/javascript" src="<jquery url>"></script>
Replace the <jquery url>
with a valid url to the jQuery library. I suggest you use the Google CDN for the url or alternatively download a copy and store it on your server -> http://docs.jquery.com/Downloading_jQuery#Download_jQuery
Then to ensure your code runs once the DOM is ready wrap all of your JavaScript within the following :
$(document).ready(function() {
// your code here
});
If your going to be using jQuery more I suggest you start reading here http://docs.jquery.com/How_jQuery_Works and if you going to learn JavaScript, you can't go wrong with reading this too -> https://developer.mozilla.org/en/JavaScript/Guide
Copy the code below, save it with a .html extension (eg test.html) and then double click to open.
<html>
<head>
<title>Page Title here</title>
</head>
<body>
<select id="t_dermal_name">
<option value="t_default_dermal">-- Choose --</option>
<option value="1" rel="30">Between Eyebrows</option>
<option value="7" rel="30">Individual Line Softening</option>
<option value="2" rel="30">Lip Contouring</option>
</select>
<select id="t_wrinkle_name">
<option value="t_default_wrinkle">-- Choose --</option>
<option value="1" rel="30">Between Eyebrows</option>
<option value="7" rel="30">Individual Line Softening</option>
<option value="2" rel="30">Lip Contouring</option>
</select>
<span id="output"></span>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5/jquery.min.js"></script><!--You can use a local version of jquery-->
<script type="text/javascript">
$(document).ready(function(){
function onSelectChange(){
var total = 0,
dermal = $("#t_dermal_name").find('option:selected'),
wrinkle = $("#t_wrinkle_name").find('option:selected');
if(value = dermal.attr('rel')){
total += parseInt(value);
}
if(value = wrinkle.attr('rel')){
total += parseInt(value);
}
$("#output").html(total);
}
$("#t_dermal_name").change(onSelectChange);
$("#t_wrinkle_name").change(onSelectChange);
});
</script>
</body>
