Hello!

I have some code that checks if a string (a user id) is not empty.  
If the string does have some value, then I advance the playhead to the “loading” frame. Otherwise, just keep playing. The code is simple. It’s in frame 3 of my timeline:

```auto

stop();
if (sessionUserId != "") {
 _global.username = sessionUserId;
 gotoAndPlay("loading");
} else {
 play();
}

```

This runs fine on my computer. However, on my co-worker’s machine, it never seems run the gotoAndPlay(“loading”) line, even though ‘sessionUserId’ has a value.

Does anyone know what might be happening? Is Flash skipping this frame?
