When using Select in a form, how do i send the multiple selections to a servlet?

Hi, I'm trying to figure out how to write a servlet that has a Select in which users can select multiple entries, and a
submit button that sends the values of the selected attributes to a servlet. Here's a simple example i tried to make,
but it doesn't work (the servlet recieves only the first of the selected items). Please help

;test.servlet
(servlet (age)
(case age ((#null)
{<html><head><title>Test Form</title></head>
<body>
<form method="get" action="test.servlet">
Select sereval of these numbers:
<select name=age size=5 multiple>
<option value=10> 10 </option>
<option value=20> 20 </option>
<option value=30> 30 </option>
<option value=40> 40 </option>
<option value=50> 50 </option>
<input type="submit">
</select>
</form>
</body></html>})
(else
{<html><head><title>Test Form</title></head>
<body>
You selected
[age]
</body></html>})))

use String array?

String[] arrValues[] = request.getParameterValues("age");

Hi bubbledragon,

The second set of brackets aren't required right? Happens to the best of us, should look like this:

String[] arrValues = request.getParameterValues("age");

I'm not really sure what you meab by :
String[] arrValues = request.getParameterValues("age");
That looks like Java.
I am using JScheme for my servlet. (http://www-swiss.ai.mit.edu/~jaffer/r4rs_toc.html)
Could you please show how and where to insert that in my code (because just putting it
in before [age] on the second to last line doesn't work).

Thanks a lot

-------------
Also, in the above code i accidentally put the <input type="submit"> inside the select.
So here's the corrected code:

;test.servlet
(servlet (age)
(case age ((#null)
{<html><head><title>Test Form</title></head>
<body>
<form method="get" action="test.servlet">
Select sereval of these numbers:
<select name=age size=5 multiple>
<option value=10> 10 </option>
<option value=20> 20 </option>
<option value=30> 30 </option>
<option value=40> 40 </option>
<option value=50> 50 </option>
<input type="submit">
</select>
</form>
</body></html>})
(else
{<html><head><title>Test Form</title></head>
<body>
You selected
[age]
</body></html>})))

...sorry, and as to where, it's at the top of the page, or really, it doesn't exactly matter where it is. I'm NOT familiar with JScheme, I'll check it out.
