Thank you for the reply, my apologies upfront for not following you.
When you say "...create a subfolder in ur app folder as blog,..." I think I've already done that on the web server, http://blog.WebApp.com is that subdomain. And in that subdomain is the code I listed above, which was supplied to me by GoDaddy but throws an error.
Could you show me a code example of what you mean?
Thank You
