HELP : Problems with conditions?

Hello,

I learned a few AS a week ago which involves variables, but this one I have in mind is too much for my little knowledge I guess.

In this example: http://www.allanrestauro.com/downloads/public/interface.swf

I wanted that when you hover on the 1st photo, that details would show (current state) and when you hover on the next photo, it will first return the original state of the first photo before showing the details for the 2nd photo. So as for the 3rd photo.

Any actionscript for this one?

Thanks,
Allan
