AS3 child issue with if statements

Alright, can someone explain what is wrong with my code below, there is no errors, but it's not doing what I want it to do. I need it to display a movieclip on the screen when a variable called "randint", which is generated by random, is greater than or equal to 0.5. If it's not then it doesn't get displayed. Code:

addEventListener(Event.ENTER_FRAME, char_coll);
function char_coll(ev : Event) : void
{
    if(currentFrame==2)
    {
        if (randint >= 0.5){
            var w1:woman1 = new woman1();开发者_如何学Go
            randint = Math.random();
            if(w1.hitTestObject(stand)){
                w1.gotoAndPlay(1);
                cash1 = cash1 + 1;
        }
        }

    }
};

randint is set inside the if statement. This means that randint always is undefiend, because it has to be >= 0.5 to be set to any value (kind of a catch 22).

This code should work:

addEventListener(Event.ENTER_FRAME, char_coll);
function char_coll(ev : Event) : void
{
    if(currentFrame==2)
    {
        var randint:Number = Math.random();
        if (randint >= 0.5){
            var w1:woman1 = new woman1();
            stage.addChild(w1);
            if(w1.hitTestObject(stand)){
                w1.gotoAndPlay(1);
                cash1 = cash1 + 1;
            }
        }

    }
};

Then of course you have to add w1 to the stage using addChild() as you can se below var w1:woman1 = new woman1();

hope it helps!
