Unloading XML files using AS2 - please help (urgent)

Hi all,

Hope you can help. I have a movie clip with 25 different frames on it. On each frame I have the usual XML loadin information pointing to different XML files on my computer. When I click one of the 25 content buttons I have told the movieclip to go to a particular frame to load a particular xml file. The problem is it won’t unload the first XML file so keeps displaying that data over and over again.

Does anyone know of any simple (only just getting to grips with AS) coding I can place on another button to unload the XML data?

Thanks for any assistance.
