[F8] help with Delaying "x" seconds using script

[cwismer]

Hi, i am working on a web banner which needs to be very small in file size. i want to tell a frame to stop and wait 3 seconds before moving to the next frame. is there a way to do that so i dont have to extend the timeline out 36 frames?

stop();
incFrame = SetInterval(nex,3000);

function nex (){
nextFrame() ;
clearInterval (incFrame);
}
