<%

sql = "SELECT * FROM tblNews WHERE ID = " & Request.Querystring("ID")
data_source = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & Server.MapPath("news.mdb")

' Creating Connection Object and opening the database
Set con = Server.CreateObject("ADODB.Connection")
con.Open data_source
set rs=server.createobject("ADODB.recordset")

rs.open sql, con

Response.Write(sql)
Response.write(rs("article_title"))


'Done. Close the connection
con.Close
Set con = Nothing

%>

The code is pretty straight forward and seems fine.

Possible ways to debug your code:

1. Make sure the request is correct.
Are your submiting actually the variable 'ID'?
URL should look via like this: page.asp?ID=whatever

2. Is the request being redirected?

3. Is the script being called in response to a 404 error?
Servers usually add the 404 error url to the query string.
This causes variables submitted to the original script to not be accessible via request.querystring
