SSI stands for server side include, which means update one page and it does the same for each page. First create a page with all your menus or navs on it. Then when your done don't add any contents like updates or anything. Then create each of your contents pages like updates, etc but instead of naming them .html or .htm name them .shtml without this it will not work. And on each of those pages insert this code. [an error occurred while processing this directive] Left.html is the name of the page you saved the menu page as. So if you saved the menu page as anything else put that in there instead of left.html.

That's about it , well you might look at this page and, say to yourself, what?, well for you too fully understand this you have to know html.

If it does not work still it is most likeky your web server does not support SSI (Example: Geocities) Geocities does not support SSI.
