i made a simple asp page, default.aspx. I saved it to localhost and ran it, i got the error "Server Application Unavailable"

I changed the extention to .asp, and it ran, but the script didnt work.

here is the script:

asp Code:
  1. <head>

  2.     <title>Test Page</title>

  3. </head>

  4. <body>

  5.     <form id="form1" method='post'>

  6.     <div>

  7.         <input type="text" name="myname" />

  8.         <input type="submit" name="submit" value="Submit" />

  9.     </div>

  10.     </form>

  11.     <%

  12.         Dim myname

  13.         myname = Request.Form("myname")

  14.         Response.Write("Hello " & myname)

  15.      %>

  16. </body>

  17. </html>
