timer weird behavior

[culter]

Hi, I have 3 frames and I need to switch between them after 5 seconds. My AS2.0 code for every frame is:

function myTimee (){
gotoAndStop(2);
}

setInterval(myTimee,5000);

of course, function name and frame in gotoAndStop changes every time. The weird thing is that it works for the very first time, but then it is going crazy.

1.2.3.
2. // here it goes to frame 2 instead of 1

3.1.2.3.1.2.3.1.2.3.
2. // this is weird too
3.1.2.3.1.
Thank you
