First I have to explain a bit of how this works. We use what’s called a URL query string, You have proble scene something like this “index.php?name=test” Were it says name is referring to the case statement. In any other example, if u were to put hello $name and use the URL file.php?name=James then the out put would be “hello James�?.

So in this case name will be the case you wish to communicate with and the page you wish to view is tutorials thus we use index.php?name=tutorials, in my case I use 2 one for content and one for sub-nav. To do this we use the & character to indicate that there is a second variable or case statement that we can’t to communicate with.

And this is what I came up with.
