Help!!! Why does the back button on my browser take me to the last site I was at???

[gillespie77]

When I am on the site I created,

www.hymarkcylinders.com

and I go to another page, say by... clicking one of the cylinders...

and I want to go back to the first page of the site by using the back button
on the browser instead of my home button that I made...

how do I accomplish this???

Do I use ExternalInterface.call....
