Need Help with Navigational System

Hey there MaNaCHa!  Thanks for popping in.  :)

I'm not sure if this is what you're after, but I've attached your project with some modifications.  Essentially, I set triggers on the base layer to change the states of each button shape to their proper format (normal, visited, etc).  I used format painter to apply the states (based on the format of Part 1's button) to each of the button shapes... some colors were off, so you might need to adjust those.  And I set the buttons (except for part 1) to "disabled" as the initial state.

Here's the important part:  those triggers to change the states of the button shapes have to come before the trigger to show the respective layer, otherwise it will jump to the layer without ever firing the state change.

On the layers, your buttons will continue to show but not be clickable because I've placed a rectangle over the top of them with a solid fill set at 100% transparency.  Invisible barrier.  ;)  I simply copied and pasted that shape to each layer once I had it formatted.

It seems to work ok for Parts 1, 2 and 3.  Let us know what you think, or if it at least gets you closer!

Oh, and I loved your use of quotation marks around "grown men."  Based on my experience, I think they'll like the Mack trucks.

Crystal,

You Are Awesome!!!!!

I totally see what you have done...thank you so much. You rocked the locked/unlocked visible states issue I was having.

Yeah, my men are drivers so I was hoping the trucks were befitting and age appropriate at the same time :-)

This made my day!!  Thanks  :)

Also Crystal, I see the reason for the invisible (light colored) rectangle barrier ...I know, I know light color and invisible = oxymoron. However, that leaves the first btn "Part One" in the green hover state and all other btns showing the 'invisible' state when visited.

Do you think the invisible rectangle is necessary because the truck icon and the solid-colored rectangle/background are two objects and not a picture?

I will test this theory :-)

I used the "transparent" rectangle to block users from clicking on any of those tabs at the top since they show through from the base layer and still retained their function.  But in the light of day (at least where I am right now), I remembered that you can actually set your layer properties to say "Prevent the user from clicking on the base layer."

So I removed that rectangle, and the effect was the same without a superfluous shape.  The color weirdness still persisted, though, and I've seen before where rebuilding a shape or a state helps eliminates any wonkiness.
