Struts and JSP problem..help needed

Question

Hi,
I am trying to use request.setParameter("formatName") from the JSP page into the ACtion class to display the user entered values.
I have my struts action classes tagged to be in session scope since the UI is a wizard and i want the values to be carried on until they click finish. on the wizard.
I want the formatName floating across the wizard, I have another value called."Category" floating since its a dynamically generated variable using the formbean.
***************ACTION class****************
public class CreateFormatReportDefinitionAction extends Action
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
     final Logger logger = Logger.getLogger(this.getClass());
ActionErrors errors = new ActionErrors();
ActionForward forward = new ActionForward(); // return value
ClarityReportDefinitionFormBean rdFormBean = (ClarityReportDefinitionFormBean) form;
          HttpSession session = request.getSession();
          List fList = new ArrayList();
          FormatDAO fDAO = new FormatDAO();
          Format fmt = null;
try {
          logger.log(Level.INFO, "Entering CreateFormatReportDefinition Action...");
          Person person = PersonUtil.getCurrentUser(request);
          logger.debug("Category is: "+rdFormBean.getCategory());
          List formats = fDAO.findFormatsForCategory(rdFormBean.getCategory());
          for(int i=0;i < formats.size(); i++) {
               fmt = (Format)formats.get(i);
          if(fmt.getOwner().getEmailaddr().equals(person.getEmailaddr())){
          fList.add(fmt);
          rdFormBean.setUserFormatList(fList);
          logger.log(Level.DEBUG,"sessionObject for formName is: "+session.getAttribute("formatName"));
} catch(Exception e) {
// Report the error using the appropriate name and ID.
errors.add("name", new ActionError("id"));
// If a message is required, save the specified key(s)
// into the request for use by the <struts:errors> tag.
if (!errors.isEmpty()) {
saveErrors(request, errors);
// Write logic determining how the user should be forwarded.
forward = mapping.findForward("success");

I am getting a null for Session.getAttribute("formatName") or even if i change the scope to request, i use request.getPArameter("formatName"), i get null again.
