I would like to help you but I don't think you have been honest with me in your last two questions.
Did you even try my suggestions. ?

rrz@871311,

My apology for that. After work when I am home I would respond.

I was under gun and have to shift my focus elsewhere, Also, there was server setup which was adjusted and the attending to the question was not priority.

I will get back to you.

Also I thing <!-- to do with sort of public deceleration or just deceleration.

I am new and confused right now.

thx

<%         %>----------------> this is scriptlet

<%!    %> ------------> this declerative  

both are usefull to right java code but the main diffrences is if you want to use any filed or method any where in jsp then you can go with declerative  .
eg:
<%! String s="Sathish" %>
<% String  s1="David" %>

here you can use s in any where in your jsp but s1 will accessable inside the scriplet only ....

thanks dravidnsr, t

o post No instead of null, I am using the following code:

      <body>
          
             <%! String str = "No" %>   <-- is this correct?
             
            <b>Margherita?:</b>
            <%
            str = ((request.getParameter("margherita") != null)? "Yes":"No");
                  out.println(str);
            %>
            <br>
            <b>Hawaiian?:</b>
            <% out.println(request.getParameter("hawaiian")); %>
            <br>
            <b>Pepperoni?:</b>
            <% out.println(request.getParameter("pepperoni")); %>
            <br>

      </body>

I want to declare str once such that its scope will hande all three items. After the first one works, I wiil change the remainig two.
