Masking problem

i am having problems with getting the desired effect from my limited knowlege of flash, i went through a few tuts to try and figure this out for my self but eh…no dice

ok i am trying for a masking effect where i will have a line drawn representation of a person and it will start with that drawing and then flash quickly from the line drawing to end up with the real pic of the person… i.e. in my fla its just some chick.

if someone could point me in the right direction or help out that would be really helpfull:q:

ok ****it i guess i can’t leave a .fla…

any pointers anyway?
