This should read like this

<%=request.querystring("username") %>


not like

<% response.write ("request.querystring("username")") %>

Also, try like:

<% response.write (request("username")) %>

instead of

<% response.write (request.querystring("username")) %>

as QueryString only get the variable when you use form method GET, to make it simple, use as what i stated there.

like:

request("username")
request("password")

Hope this helps

try to do the following:

<form name="form1" method="post" action="login.asp?username=<%=request.form("username")%>;password=<%=request.form("password")%> >

<input type = "text" name="username" >
<input type = "password name="password">
<input type = "image" name ="submit" >

or

<form name="form1" method="post" action="login.asp?username=<%=strUserName%>;password=<%=strPassword%> >

<input type = "text" name="username" >
<input type = "password name="password">
<input type = "image" name ="submit" >

<%
Dim strUserName, strPassword
strUserName=request.form("username")
strPassword=request.form("password")
%>

also make sure request.querystring("username") is not blank before you print it out.

Another suggestion I'd like to make is do not pass your password as a querystring. It's not secure.
You could use session objects instead

just a note on previous comment
Session objects are server side objects one needs ssl for that security

and now the main question WHY NOT WORKING?
it is not working because you are trying to use 2 different methods of passing data together.
One is a post from a web form and another using a url enoded variables.
Judging from your question I think you need the posting
solutions given below

the lines
          <form name="form1" method="post" action="login.asp>
is all u need the rest of the values are encoded and submitted by the browser

                       ----------------------------FORM-----------------------------------
                      <form name="form1" method="post" action="login.asp">
                      <input type = "text" name="username" >
                      <input type = "password name="password">
                      <input type = "image" name ="submit" >

                     ----------------------------login.asp--------------------------
                     <%
                            DIM username, password
         
                              username=Request.Form( "username" )

                        %>
                    ----------------------------------------------------------------
Now u can write it with a response write it with a responce object like this

or you can simply put a asp tag in html page any where u want it like this
                -------------------------------SAMPLE-------------------------------------------------------
                <body>
                 hi this is some formated tect and i shall tell u your name is  <%>=username<%>
                </body>
 
                 ----------------------------------------------------------------------------------------------
the benifit of this approch is we can use a WYSIWYG editor to format the pages responce.write should be used when u want to output a complete page or formated html output say when you are working on a templet system.


---------------------------image submit------------------------
I also think you are trying to use an image as submit button instead of a button
if so u shall need to enclose it in a address tag and put a javascript see example below

<img src="image.gif" width="x" height="y" border="0">
<a href="javascript:form1.submit();"><img src="image-name" border="0"></a>

Like j_chakraverty said there's 2 methods to post the data and coz of that there's also 2 ways to parse the data.

Your form is using method POST and on your asp page you're trying to read the data from URL when POST method actually doesn't put the info in URL. If you want the info to be in URL then you must use method GET with your form then you can parse the data like you did with request.querystring("username") etc, but i don't recommend you to keep username etc on URL so change the method to POST and use the sample which j_chakraverty gave to you.

just to make it simple, why don't you add a 'value' attribute to your inputs ?

<form name="form1" method="post" action="login.asp">
just one thing the correct syntax is PATH?var1=this&var2=that&... forget about the ';'

<input type = "text" name="username" value="<% =request.form("username"); %>">
i'm not good on asp so just check out if it echoes the needed value allright


<input type = "image" name ="submit" > :(( no good at all, see below

<input type = "image" onClick="javascript:document.forms.form1.submit();" src="..."> (you can add the name attribute but it's useless, you should prefferably use a IMG tag with the onclick and src attributes)

<input type="submit" src="..."> will work on some browsers but not good at all either

<a href="sendtoerrorpagesayingthatyouneedactivejavascript" onClick="javascript:
document.forms.form1.submit();
this.href='#';"><img src="whatever"></a> will let you intercept non javascript-compliant surfers and will show the little hand when you put your mouse over the image !!

the best : just don't use an image for this purpoise when you don't need or just store the image as a background for a simple <input type="submit"> prefferably using CSSs. the image will only be displayed to recent browsers but older ones and javascript-forbidden clients will still be able to press the button !!

==========
login.asp
<% response.write ("request.querystring("username")") %>

of course you can only use this with the 'get' method
btw even with the get method you should not try to store variables in the 'action' attribute of the 'form' tag
just use <input type="hidden" name="variable" value="the_value">

try html forms in google and read a tutorial will prevent you from mixing asp and html problems too often

thanks everyone ,  I chose to use this method  and it works perfectly :

<script langugage = "javascript">
function form_submit()
{
form1.submit();
}
</script>

<input type = "image" img src = " ../" name = submit onclick ="form_submit();"> // call submit function//

or

<input type...                  onclick ="javascript:form_submit();">

<form name="form1" method="post" action="login.asp"> //posting method//

login.asp
=====

request.form("username")
request.form("password")

and done :)
