i dont understand what is the meaning of " \_root.section" whats is the mean of the " section"
and i put this script:
onClipEvent (enterFrame) {
if (!loaded && this.\_url != \_root.\_url) {
if (this.getBytesLoaded() == this.getBytesTotal()) {
loaded = true;
\_root.transition.gotoAndPlay(“opening”);
}
}
}

\_root.section is a variable
Select the “transition” MC ont he state and doubleclick on it. You can find another code in the timeline of that
[CODEloadMovie(\_root.section, \_root.content);\*\*[/\*\*CODE]
The loadMovie () usually take three parameters is first is url, taget and method.
You can using Flash’s MovieExplorer from window menu to find any instance has a physical existence in the movie. I’ve give the name “transition” in the explorer window and that displays the instane name and the objects actually name in the library. :inc:
