How to use Flash Object on a counter bar

So, I am trying to make a counter bar "pulse" when it reaches full. I have figured out how to set its ink effect and change its color. Now I am trying to see if Flash Object will be enough to make the bar flicker when it is full, but when I enable it, it just turns the bar off. I set the interval to 1/2 a second (50/100). Is there some other voodoo I need to do to get it to work?

Also, if I want to make a smoother pulse than what Flash Object can give me, will I need to create a bunch of Set Color/Transparency events? Or is there an easier way with a mathematical formula that will interpolate between colors?

I haven't tested this myself, but is it possible that you're continually performing "Flash object" on the object, so that it begins flashing (as invisible) all the time?

Flash Object just turns the object's visibility on and off depending on the interval you give it rather than pulsing - perhaps you could always set its transparency to gradually rise and fall based on some formula.

You could make a duplicate counter/active as the flashy object and show it hide it.

I guess I really just want to see the Flash Object command working so I can evaluate if I like it or not. Since the help file kind of states the obvious in its description of it, I assume the object should be blinking from visible to invisible (to visible to invisible...etc) at the set interval. Since it isn't doing that, I just thought I might not be using it correctly.
