Hi I'm a Javascript newbie. I am displaying list of things in my Jsp page. each row has two drop down menus and a radio button. When the submit is clicked it sends the index of the radio button clicked as a hidden parameter. I need to get the drop down menus selected value in the servlet. It seems to be working only for the first item in the table. If i choose the second item and choose something in the drop down menu...when I access it in the servlet it has the first value that is in the drop down no matter what I select.

Please help. I have no clue what the problem is :(

<form  name="cart" method="post" action="listTechnicians" >
    <h1>List Books</h1>
      <table border="1" cellpadding="0" cellspacing="0" width="100%" id="bookTable">
             <th align="center" width="15%">Book Id</th>
             <th align="center" width="40%">Initial Title</th>
	    <th align="center" width="15%">Next Task</th>
	    <th align="center" width="15%">New Status </th>
             <th align="center" width="15%">Assign Book</th>
             <th align="center" width="15%">Curr Status</th>
             <th align="center" width="40%">Title</th>
	    <th align="center" width="15%">Admin</th>
	    <th align="center" width="15%">Galley</th>
	    <th align="center" width="15%">Design</th>
     <% // java loop 
     int numOfItems = shared.getBooksCount();  
     if (numOfItems >  0)
            String bookid, initialTitle, title, design,galley,admin, status;
            for(int i=0;i<numOfItems;i++) {
               bookid = shared.getListItem(i,0);
       	       initialTitle = shared.getListItem(i,1);
	       title = shared.getListItem(i,2);
	       status = shared.getListItem(i,3);
	       admin  = shared.getListItem(i,4);
	       galley = shared.getListItem(i,5);
 	       design = shared.getListItem(i,6);
           <td name="id" align='center' valign='center'><%=bookid%></td>
           <td name="initTitle" align='center' valign='center'><%=initialTitle%></td>
	  <td align='center' valign='center'><select name="nextTask">

           <td name="assign" align="center" valign="center"><input name="book" type="radio"></td>
                <td name="status" align='center' valign='center'><%=status%></td>
	       <td name="title" align='center' valign='center'><%=title%></td>
	       <td name="admin" align='center' valign='center'><%=admin%></td>
	       <td name="galley" align='center' valign='center'><%=galley%></td>
	       <td name="design" align='center' valign='center'><%=design%></td>

       		<%} // end for loop%>

Here is how I am getting the drop down values in the servlet

String nextTask = request.getParameter("nextTask");
        String newStatus = request.getParameter("newStatus");

From what I see you have your select tags inside a for loop?
That would mean that the html generated will have more than one <select> tag.
If you use the request.getParameter, it will always return the first value.
But you send at the request many <select> "items" with name nextTask and newStatus.
So I would suggest to use the method that returns an array of value.

If I remember:

String [] nextTask = request.getParameterValues("nextTask");

I am not sure about the method. Check the API for the method that returns an array of Strings.

Another thing you could do is this:

<input type="hidden" name="numOfItems" value="<%=numOfItems%>" >

<select name="nextTask_<%=i%>">


int numOfItems = Integer.parseInt(request.getParameter("numOfItems "));
for (int i=0;i<numOfItems ;i++) {
  String nextTask = request.getParameter("nextTask_"+i);
