Filling in my shapes

Hi guys! i’m new to flash…sorry!
i have a really basic question…
i’ve made my character on flash and i can’t seem to fill in the shapes with colors…i keep using the paint bucket to fill in but it wont let me.
It has something to do with the layers i presume cuz the shapes i wanna fill in has a huge gaping hole but my other layer covers it. do you get what i’m trying to say?
if i select the layer by itself, it has holes. but looking at the whole thing together, no holes. How do i fix it??

THANK YOU!!
