Stobe effect and playing multiple clips

i just started learning to work with actionscript so im not that good

i have 5 movieclips on the bottom on the site im trying to make
i want them to blink in order first clip to th eother.
so when the first one is done blinking i want the other one to do so, and so on untill they are all done

this is the code i got for strobe like effect, but im not sure how to use it with multiple clips so they dont all do that effect at the same time

the code iis


cir.step = 0;
cir.seconds = 1;
cir.framespersecond = 30;
cir.f = 0;
cir.strobe = [0, 100, 10, 30];
cir.onEnterFrame = function() {
        this._alpha = this.strobe[this.step];
        this.step += 1;
        this.f += 1;
        if (this.step == this.strobe.length) this.step = 0;
        if (this.f == this.framespersecond*this.seconds) {
               
                delete this.onEnterFrame;
        }
};

thanks for the help
