[f8] button rollOver show's movie. How to unshow movie on rollOver other button

[eyedynamic]

I've made a productoverview in flash.

There are 4 productphoto's (buttons with just a rollOver-function, no clicks).

Behind every productphoto there is a detailed product-specification (movie) that shows up when rollOver on the productphoto's.

So I want the product-specification movie to appear when theres a rollOver on the productphoto. The movie has to show on rollOver and has to stay visible on rollOut. But when u move to the next productphoto (rollOver) the previous product-specification movie has to disappear and the new one has to show.

I don't know what to do. so far i have this:

on (rollOver) {
tellTarget ("sony-1-1") {
gotoAndPlay (2);
}
