Try replacing "MydbFilePath" with the actual hardcoded path of the access DB.
If you do response.write MyConn.State straight after your MyConn.Open, this should output a '1' or 'true' so you know you have an open connection
Within your tags, try referencing your recordset fields like this: -
<%=rs.Fields("Country")%>
If you run the same query in Access, do you get results?
Hope this helps
