Creating catch game

1

would anyone be able to provide a model of the actionscript for how to make a catch game like http://www.mathplayground.com/multiples.html
i need to have this in for a school project in one and a bit days time, and i will fail otherwise, and i have no idea how to do the actionscript involved for making the objects fall with differing numbers from the top of the stage. if anyone can help me i will be forever grateful!!!

the code i am using currently is

depth = 0;
function makeNewClip() {
    clearInterval(ranID)
    ranID=setInterval(makeNewClip, ran)
    newClip = _root.attachMovie('ddrop', 'ddrop'+depth, depth++);
    newClip._x = Math.random()*Stage.width;
    newClip._y = -50;
    newClip.speed = (Math.random()*10);
    newClip.onEnterFrame = function() {
        this._y += this.speed;
        newDrop = _root.attachMovie('ddrop', 'ddrop'+_root.getNextHighestDepth(), _root.getNextHighestDepth());
        newDrop._x = 100;
        newDrop._y = -50;
    newDrop.number_txt.text = Math.ceil(Math.random()*10);

    };
}
makeNewClip();
setInterval(makeNewClip,2000);

i cant get the dynamic text i’ve placed in the movieclip of the falling objects to work, and am questioning whether there is a better way to tackle this problem?

thank you in advance for any help you can provide!
