Why my JSP page can't get the value of a hidden field

Question

Hi, I got an interesting question here.
I use req.getParameter() method to get a hidden field in Servlet, it works just fine.
However, when I use the JSP to catch the value of that hidden field, JSP just can't, but if I change the type from hidden to text, it works fine again.
the code is as follows:
there are two jsp pages:game.jsp and GameMonitor.jsp.
In game page:
============================================================
<FORM action=GameMonitor.jsp method=post
webbot-action="--WEBBOT-SELF--">Display the names of all the players currently
connected to the server       <INPUT tabIndex=1 type=submit value=Lookup name=B1>
<INPUT TYPE=hidden,value=1 name=p1>
<P></P></FORM>
===========================================================
I want GameMonitor.jsp to catch the value of hidden field "p1" by calling request.getParameter()
the code catching it in the GameMonitor.jsp is:
============================================================
String option = request.getParameter("p1");
          out.println("option=["+option+"]");
          try{
               if(option.equals("1")){
===========================================================
supurisingly, the result is option=[], which means it didn't catch the value of the p1 submitted by POST method.
Does anybody here can tell what's wrong in the code?

Thank you so much, I also found this error, which makes JSP not able to catch the hidden field, however, if I change it to text type, even the comma exists, it still works. pretty interesting!

<INPUT TYPE=hidden,value=1 name=p1>Modify the above lline and write like this....
<INPUT TYPE="hidden" name="p1" value="1">
And ensure that you're submitting the form data.
Though nothing much has been changed, just try whether
these help!!!
