How do I set this for random 1

[dmacster]

I found this AS source (still have MX and do almost no flash work) online, and am wondering if someone can tell me how to set for random images. Perhaps a brief explanation - I've stared at the comments for 2 hours and cannot fathom what to set.

What is the problem? The code should generate a random number (although it's not the best way to generate it) and load images accordingly.

It just goes through sequentially. I'm not sure what to change to make it random.

Thanks,

Is your XML set to "random"?

Ooooh - I'm an idiot. Thanks for pointing that out. I was using an old xml file.
