Multiple xml and flash photo galleries

i am extremely new at this…so thank you so far for the tutorial for the xml and flash photo gallery…my question has to do with having multiple galleries on my website. how can i do this? i dont understand how to point flash to different files (the tutorial had ‘images.xml’) but to have separate galleries i need an xml file for each gallery. action script is still very confusing to me at this point, but any help would be fantastic…thanks again.
