Help with modifying Photo gallery

I am very very new to action scripting and flash. I am not asking anyone to write the code to my question at all I am just asking for tips on how to do it. Ok so here is the question, I have already completed the photo gallery w/ thumbnails successfully but i would like to modify it so that I can have the user be able to view different photo albums by selecting one from a combo box. I would also like the pictures from the album that is selected to load in the thumbnail scoller. I having to make multiples of the same swf to display different photo albums i want to put it all in one place. I have also modified the xml file by adding the tag <folder name=“what ever”></folder> to declare whhich album is which. I will thank ever one for teh help that they give me but would like to thank everyone now for taking time to read this.
