Another XML Thumbnail Gallery Question

Okay, so i originally had a long winded question that i figured out after all, so i kept working and working and i’ve got another problem that will take more research, but since i already posted here, i thought i should just ask you guys, as i’m finished for the evening.

Anyways, i’m working on an XML driven thumbnail gallery, where the thumbs are in a grid. I have all that working, now i want the ability to have the thumbnails load, and there to be scrollbars if the amount of thumbnails exceeds the masked area where i want to keep the thumbnails. I worked through the scrollbars tutorial on here, and that seemed promising, but for some reason the up and down buttons won’t work correctly, when i press the down button it just jumps too low and there is nothing to be seen. My guess is that since the thumbnails are loading dynamically the size of the dynamically created thumbnails_mc movie clip isn’t determined when the scrolling function goes to work. I guess what i need is a way to have the scrolling function initialize when the thumbnails have all loaded in place…does that make sense?

p.s. this is the best site for flash out there, i’ve learned a great deal, thanks.
