When working in the ASP environment, HTML forms are used to pass data from the client browser to the Web server. If the form variables are passed to the Web server using the GET method, then the variables are read from the QueryString collection. In this case, you should retrieve the value from the QueryString collection:

  sVariable = Request.QueryString("txtVariable") 

However, if the variables are passed to the server using the POST method, then the values will be in the Request object’s Forms collection. In this case, you should retrieve the value from the Forms collection:

  sVariable = Request.Form("txtVariable")
