I'm using LoadVars in Frame 1, and I need to use the resulting variables in
other scripts afterwards. (But all the examples I find online only use the
variables right in the same script.)

The problem I'm having is, the onLoad function doesn't actually make it wait.
It goes ahead to the next frame whether fully loaded or not. It depends on the
connection at the moment--if the vars haven't fully loaded, hilarity ensues.

My script in Frame 1:

_root.myloadvars = new LoadVars();
_root.myloadvars.load("datapairs.txt");
_root.myloadvars.onLoad = function(success) {
 if (success) {
 //trace("TXT RETRIEVED");
 gotoAndPlay(2);
 } else {
 trace("TXT NOT RETRIEVED");
 gotoAndPlay(1);
 }
};

It's SUPPOSED to hold in Frame 1 until ready to proceed and make use of the
variables in Farme 2.

Things I have tried:

* Moving the above to Frame 2, so the "not retrieved" loop actually has two
frames to cycle (back to 1, then forward to 2 where the script it).

* Adding an additional gotoAndPlay(1) BELOW the above.

But regardless, it never goes back to Frame 1, it always goes forward. It
reports success, but half the time the variables (or some of them) are still
Undefined.

What's the RIGHT way to wait in a frame for LoadVars, and then let other
scripts use the variables afterwards?

Many thanks for any advice!

(PS, this is Flash MX--I'm waiting for Universal Binary before I upgrade.)

this may not be what you are looking for or even the right idea but why
couldnt you just use a preloader to wait until it is finished loading
the variables?

You need a stop() on the frame doing the load and onLoad. Then in the onLoad
you move to the next frame. Other approaches include hiding the UI and in
the onLoad, revealing the UI such as a MovieClip cover is made invisible.

Declare the results LoadVars object on the timeline outside of a function
and it is accessible for the entire movie at all levels.
