Checks to see if MC arrived

I have a MC moving via script as follows


onClipEvent (load) {
        cont = -675;
}
onClipEvent (enterFrame) {
       //movement code here
} 

Then on the next frame I have


if (cont < -673) {
	nextFrame();
}

So basically what I’m trying to do is get it to play the nextframe once the MC has reached the point -675 … anyone know what I’m doing wrong here?

PS- “cont” is the instance name of the MC
