    I am trying to display the old varible in the text field and after the user changes the varible in the text field, the new varible will display here

    please look at my code:

    <html>
    <body>
    <form action="a.asp" method="post">
    Your name: <input type="text" name="fname" size="20" value="<% response.Write(fname) %>" />
    <input type="submit" value="Submit" />
    </form>
    <%
    session fname
    fname=Request.Form("fname")
    If fname<>"" Then
    Response.Write("Hello " & fname & "!<br />")
    Response.Write("How are you today?")
    End If
    %>
    </body>
    </html>:confused:

    you'll probably get someone else saying this to you far less eloquently, so...

    a) Variable is spelt as such.
    b) Use [ CODE ] [/ CODE ] tags

    Im no good at ASP, but what does 
    session fname
    do?

    I believe it creates a session with the value "fname"

    [edit] I was wrong :( [/edit]

    Session fname doesn't do anything
    Session("fname") = Request.Form("fname") will set up a session variable with the passed form's fname's value

    You posted this already - and I presume a Mod deleted it. (It is simplistic code and could suggest that you didn't RTFM or STFW before posting here).

    So, I'll point you in the right direction and leave you to work it out from there...

    At this line...
    <input type="text" name="fname" size="20" value="<% response.Write(fname) %>" />

    ... nothing gets written. This is not because the Response.Write call did not execute - it is because the fname variable does not hold a value. It is empty.

    The question is - why is it empty? Why hasn't it been populated?

    I have to agree with Stipey on this, you obviously haven't put the work in and are now trying to meet a deadline. I'd even hazard a guess due to the simplicity of the code and question that this is homework or a small project for college. You need to go back to your course book or manual and start from the top. Try remembering a few simple things:

    1. You shouldn't reference a variable before you set it
    2. You can't drop variables in the middle of HTML and expect them just to write to the screen
    3. If you want your code to do something make sure that you've told it to do it - don't expect it just to know

    Coding is not easy to just pick up and it takes a certain type of person to 'get' it, but if you don't put in the work you will never if you have what it takes. Take it step by step, don't be afraid to make mistakes and if you have web access try sites like www.w3schools.com or www.aspfree.com for tips and suggestions.

    Best of luck.
