Two Submit Buttons

Hello,

I have to "submit" buttons on my servlet:
----------------------------------------------------------

out.println("  ");

out.println("");

----------------------------------------------------------

They send me to a JSP page that looks like this:

------------------------------------------------------------
<%
//////////////////////////////////////////////////////
// All of this just increases/decreases //
// the page count so that it //
// knows to go to the next question. //
//////////////////////////////////////////////////////

String pageCounter = (String) session.getAttribute("pagecount");
int pageCount = Integer.parseInt(pageCounter);

String Add_Sub = request.getParameter("move");
String Add_Sub1 = request.getParameter("prev");

pageCounter = String.valueOf(pageCount);
session.setAttribute("pagecount", pageCounter);

%>



------------------------------------------------------------------

Now what I need to do is increase (if they click the Next Button) or decrease (if they hit the Previous button) the pageCounter by 1 (--/++).

Any suggestions?

Thanks,

Brian

Try using a session variable in jsp. Look at this page http://www.jsptut.com/Sessions.jsp for some information.

Hope this helps you out.

name them both (submit buttons) name="move"

in the jsp page

[code]
String resp=request.getParameter("move")?request.getParameter("move"):"";
if ("Next".equals(resp)){
pageCount++;
}
else if("Previous".equals(resp)){
pageCount--;
}

[code]
