No problem. It's rather straight forward just play with it & I think you'll see how things click. If you have anymore questions let me know.
Thanks again Rovino, I have been playing around and nearly have exactly what I want apart from one small catch ...
I would like the transition to go from the middle outwards. Under the "Flip Order" drop down there is no option for this. I have tried using the gradient option and have animated a white circle expanding on a black background but that doesn't seem to help.
