mirror surface

I am learning surfacing.  My first challenge is to make this type of part.

I've made this so far:

I have mirrored the indent on the side.  I can see a faint line on the top side where the mirror indent should be and I can see that the indent on the bottom but I can't see the indent on the top.

what am I doing wrong?  File is attached.
