A common question I get a lot is why ASP code isn't executing properly. The users see the ASP delimiter tags when they view the source code of their page and can't figure out why the code isn't running.
The basic problem here is that if you're seeing ASP delimiter tags in your HTML output, that means that either the page is being run through a server that doesn't understand ASP, or, more likely, you aren't running the page through a server at all.
The easy way to test the second case (which is the most likely one) is to look at the URL entered in the Location or URL box on your browser. If it doesn't start with http, you're probably viewing a file directly and not through the server.
Another reason for ASP not executing: the file is not suffixed with .asp. You can use IIS's console to configure additional file extensions to use for ASP applications; however, a common mistake is to put ASP into HTML files and forget to change the file extension.
