A Little help Please

Sorry If I post in the wrong place…and hello to all…

Im trying to teach myself how to use flash with an old version, 2004…and although my requirements are fairly simple or at least I think they should be.
My lack of knowledge has bought me to a halt…

My question has to do with tweened buttons that call an element onto the stage from right , on centre stage this called element stops centered. This is as far as I get…What I would like to happen is ,on the press of another tweened button the element from first tweened button vacates left and is replaced with called element from this button, and so on for 5 seperate buttons, of course these can be pressed in any order…

I know its probably simple, but my knowledge is very limited…

Any piont in the right direction would be appreciated…

Thankyou

Shawn
