Simple variable issue

This is a simple task, but it is not working for me, thus I am forced to inquire...

-On the main timeline I can place an instance of a movie and name that instance "square"
-On the first frame of the timeline in square I can declare a variable named "cat" and assign it the value of "13"

var cat = 13;

-On the first frame of the main timeline (with the square movie instance present) I can place this code...

trace(square.cat);

And yet it will still output "undefined"

What am I doing wrong?

Thank you for your time. Best Wishes to you all,
Eric

well Eric,on the first frame if the timeline u gotta put just
cat = 13;
and then
trace(cat);

you might need an onEnterFrame handler, but check it out to see if it works

Thank you for your reply.
I understand that that would work (declaring the variable on the main timeline as well), but isn't it possible to call upon and refernce variables from the main timeline that are declared NOT on the main timeline, but instead in a movie clip instance that is placed ont he main timeline through dot syntax?

It's not calling the variable correctly because it's attempting to access it before the movieClip that you have the variable in has been initialized

I thought for sure that this was it, but even when placing the "square" movie clip from frame one to frame 10 and placing the actionscript on frame 10, it still outputs and undefined variable. What has to be done to make sure the movie has initialized the movie clip first?

just humor me
if you write

code:

---

this.onEnterFrame=function(){

trace(square.cat)'

}

Thank you, it worked. :) I was just confused, as Colin Moock's book didn't mention needing to do that, and just said use movieInstanceName.variable to call the variable. Though I would like to mention that Moock absolutely rules, and this book is great.
So I still don't understand the logic per se of why onEnterFrame was necessary, it did indeed work, so I'll use it from now on. It helped to add
delete this.onEnterFrame;
so that it didn't repeate the variable endlessly.

you dont need to write onEnterFrame.. its just that your movieClip was being initiated after your variable call to it..
