List Box problem

[Giri Mysore]

I have two list boxes i am moving selected data from box1 to box2. When i try to read box2 value at server side i am not getting that. But i am getting box1 values. Here is the code.
Vector travelStaffVector = TravelStaffCollection.travelStaffCollection;
for (int i = 0; i < travelStaffVector.size(); i++)
{ %>
<option VALUE="<%=((TravelStaff)travelStaffVector.elementAt(i)).getAssociateID()%>" >
<%=((TravelStaff)travelStaffVector.elementAt(i)).getFirstName() + " " + ((TravelStaff)travelStaffVector.elementAt(i)).getLastName()%>
</option>
<% } %>
</select>
</td>
<td>
<a href="javascript:moveIt( newassignmentform.fieldFrom, newassignmentform.fieldTo )">>></a>
<br>
<a href="javascript:moveIt( newassignmentform.fieldTo, newassignmentform.fieldFrom )"><<</a>
</td>
<td><p class="celltxt"><b>Selected Travel Staff:<br>
<select name="fieldTo" size="5" style="width:200;">
<option VALUE="">return javascript:moveIto( newassignmentform.fieldFrom, newassignmentform.fieldTo ) </option>
</select>

Here is javascripts
function bumpUp( box ) {
for( var i=0; i<box.options.length; i++ ) {
if( box.options[i].value == "" ) {
for( var j=i; j<box.options.length-1; j++ ) {
box.options[j].value = box.options[j+1].value;
box.options[j].text = box.options[j+1].text;
}
var ln = i;
break;
}
}
if( ln < box.options.length ) {
box.options.length -= 1;
bumpUp( box );
}
}
