Cannot Create MouseOver on NavBar

[hardot]

I've been trying once again (after several months away from XWD) to create a new website with a simple nav bar, using my own color schema, but cannot get the mouse over effect to work The .web file of the home page is attached. What is the step-by-step process to achieve a different color scheme for the mouse over as opposed to the mouse off? I've experimented with different layer steps, but every time I attempt to change the color of a separate MouseOver layer, that changes the color of both layers and wipes out the text on it, to boot. I'd like to use the same text color (white) on both layers - just different fill colors. I guess if I can get that working, I could add the mouse down layer as well. HOW?

Any help much appreciated.
