delaying statements - Macromedia Flash

I created an example of what you can do
http://www.shan-dysigns.com/flash/alphaYoYo.fla. I made a note in the code and
also placed a box on the stage to show you what's going on. Let me know if this
helps yoyo, I mean you... that was funny...

Shandy, I appreciate the time and effort you put into responding to my posting.
Thank you. I'm a newbee to AS, so I don't quite understand all the lines in
the code you provided me. I kept researching this issue after submitting my
posting and was able to use the code below that seems to do the same thing.

I've now ran into another issue . Now that I have mc_1 fading in/out, I
want it to fade in, wait for 5 seconds, fade out, and wait for 20 seconds
before looping. Currently, the amount of time that it waits between fading in
and fading out is the same. In other words, I want mc_1 to be fully visible
for 5 seconds and once it fades out, fully invisible for 20 seconds, and then
loop again. I hope this makes sense.

Thanks again Shandy.

myFunction = function():Void
{
myTween = new Tween(mc_1, "_alpha", easeNone, 10, 100, 2, true);
myTween.onMotionFinished = function():Void
{
setTimeout(delayYoyo, 5000); // delays myTween.yoyo for 5 secs.
}
delayYoyo = function():Void
{
myTween.yoyo();
}
}

myFunction();

The script you attached is just another way to do it (a little more compact in
design), but whichever way you understand is best. I took the code you attached
and added additional code to create the effect you want. I added notes within
the code. You can re-download that link for the new flash file. Let me know if
this is what you are after.
