XML help needed

I have portfolio presentation with navigation in which my client would like to control the items. So I set up the navigation in the portfolio section to be XML database driven that way they can pick and choose what to show at each presentation. I have set up each item as an SWF with rollover and actions, etc. They seem to function fine until I go to choose a second item and the first one remains at it’s overstate. Upon making a second selection, how can I tell the last SWF to go back to it’s original state. Is this even possible to communicate with an SWF that was brought in by XML?
