Not able to fill outlined graphic

[notJenn]

I created this simple graphic with a mix of the straight line tool and the shape tool. Any color I drag on to any panel of this hat only changes the background color. I've made sure that all these lines have snapped to the appropriate edges and have tried many combinations of joining shapes and converting to shapes, etc...

I'm new to Xara and have been using Flash for quite some time, and have noticed the vectors don't seem to work the same so I'm not sure this is even possible. Any suggestions are appreciated!
