drop down boxes with multiple select

[wxdqz]

I have created a drop down box where you can select multiple entires. I do not know how to pass the array of entries that was selected so that I can process it. Here is my code for the box:
<select name="asdArray" multiple="multiple" size= "10">
<%
for ( int i=0; i < count; i++ )
{
list = userAsdBean.userAsdArea.getList__Data(i);
String s = list.getAction() + " " +
list.getCli__Apl__Seg__Val() + " " +
list.getGroup__Name() + " " +
list.getGroup__Desc();
%>
<option value=http://www.webdeveloper.com/forum/archive/index.php/"<%=i%>" >
<%=Util.replaceHtmlChars( s )%>
</option>
