Check if MC has movie loaded...?

[LEFT]Hi people of Kirupa…[/LEFT]

[LEFT]I’m doing a friends photograpy site that has a slideshow. [COLOR=#7d7b84]http://www.wowernfoto.dk/test[/COLOR]
This slideshow is loaded into a containerclip on the mainstage.
Another container clip loads the site content (services, contact etc.)[/LEFT]

[LEFT]But the site also has a gallery which unloads the slideshow mc, as the gallery takes up that place too.
Now… i need the buttons for Services, Contact etc to check if the slideshow mc is loaded into the holder clip, and if not then load it aswell as the related content.[/LEFT]

[LEFT]I need it to check if the slideshow is already loaded, so i don’t reload the slideshow everytime a button pressed.[/LEFT]

[LEFT]Something like:[/LEFT]
