Can anyone help here please!?

see the home page banner is animating nicely

and the start of a navigation graphic lingering around at the bottom towards the right

This is meant to change when the banner changes and be able to change the banner when clicked...

Any advise on making this work would be very useful - spent a couple of days and can't seem to quite get it!

Thanks
