Trouble Loading thumbnails from XML in Flash as3.0 -

i have made gallery script loads xml large image, text, , 3 thumbnails. having trouble getting thumbnails load reason. have 3 thumbnails should previous image, current image, , next image. except when click on current image should load random image. buttons work if try load thumbnails. don't appear.

to load thumbnails have created loop array of thumbnails , number of image recorded variable noofimage. load other thumbnails subtracting 1 noofimage if prev button clicked(mousewheel down or key dwn or key left) , adding 1 noofimage if next button clicked(wheel , keys...)

when trace variables thumbnail number seem correct @ times , other times receiving errors.

for ex. if load swf , click next. previous image "4294967295" , next 1 outputs "error #2044: unhandled ioerrorevent:. text=error #2035: url not found."

if value of nextimage = 1 dont see why isn't loading. , why giving weird number should 0? can not tell if problem if statements use handle noofimage variables or if has loaders or thumbnail containers... keep trying can think of. original version loaded thumbs loop , worked having trouble making them clickable buttons , decided make simpler.

here example of how far i've gotten script. http://soulseekrecords.org/psysci/portfolio/portfolio.swf

below code sorry if messy or unclear. try best.

you're there in tracing out thumbnail value. next step trace out actual url trying load.

doing show referencing. looks tracking previmage, , setting number of images when less 1. array of thumbnails zero-based though, 3 thumbnails, thumbs @ 0, 1, , 2 , trying load dinames[3].

changing loadersnlist function previmage = totalimages-1; should fix it.

as aside, i'd suggest placing asset creation code in layout function, , once has been added stage calling loader functions pull in data.
