Snow flakes tutorial problem

Hi. I`m sorry if i post in the wrong thread but this involves action script.

I have used the tutorial from http://www.kirupa.com/developer/flash8/snow2.htm and works just fine but …

i whant to make that snow fall set between layers because i have a girl who is standing by the window looking outside so, i want to put the paisage as background, snow next, and after that the girl and windows.

All is prepared just that the snow falls over all the graphic and i don`t know how to place the snow between bg and girl.

Im new in flash and im using Flash 8.

Please reply with some pointers as soon as you can. Thank you.
