Data Access Pages with ASP.net websites

Question

I am developing an ASP.net website with a SQL server datasource. I designed a data access page with msAccess to retrieve data from more than one SQL table, then saved the html page to the ASP.net website. This seems to work fine without any exceptions thrown. However, the source code shows intellisense red lines in some areas, and there is no runat="server" tags. Can I expect any errors when this website is running on a production server. It is running fine on my local development server.

Thank You for any expert advice,
