This is what I don't like about those interfaces. They take control over the application and apply their own rules. As there were too many restrictions and as I was not able to include all the HTML tags as I use to in the old ASP page, I simply got rid of all that and added this generated HTML code directly from a GetHeader() and GetFooter() from my main object.
