Default Simple mask won't "mask"

Hi everyone. I'm trying to learn more Actionscript and I have a very simple program that is not working. My ultimate goal is to manipulate a mask so I can impart movement to it so it reveals in a eyecatching way.
But, for starters, I can't get my very simple program to run.

I have three elements in the library; a background picture, a picture to be masked, and a square graphic about 50px by 50px which is to serve as the mask; all are typed MovieClips and have a linkage class matching their symbol names.

Here is my Actionscript code:

/*instantiate the movieclip classes */
var bk1:MovieClip = new backgrd();
var pic1:MovieClip = new picture();
var mask1:MovieClip = new squaremask();

/*specify positioning */
bk1.x = 275;
bk1.y = 200;
pic1.x = 275;
pic1.y = 200;
mask1.x = 275;
mask1.y = 200;


/*add them to the display list */
addChild(pic1);
addChild(bk1);
addChild(mask1);

/*set the mask property
pic1.mask = mask1;

When I test my fla file, all I see is the background picture; there should be a square in the middle that reveals the target picture "pic1".

Would appreciate any comments,

Try this. I just did a quick google search. I believe this is what you are trying to attempt.

ActionScript Code:
// Create mask var maskObject:Sprite = new Sprite(); maskObject.graphics.beginFill(0xFF0000); maskObject.graphics.drawRoundRect(myMC.x, myMC.y, 453, 290, 20); // Apply mask myMC.mask = maskObject;

background is on top of the masked picture. (obscuring it)
add the background to the displaylist before you add the picture and mask.
