functions don't display global vars

[compuboy1010]

For some reason the functions in the movie "mcProduct" are not called or they don't display the data. Why not?
The vars are global so why don't they display them? Or is the path to the textfields wrong? Also when a leaf of the tree is clicked the mcWelcome clips is supposed to fade away and then the product description is supposed to display but after it fades out I still have to doubleclick on a leaf of the tree and it will only load the mcProduct clip but not display anything.

And this is the code on the main timeline of mcProduct.

}

_level0.main.tTest.text = sProductName;
}

function displayDescription():Void {

this.createEmptyMovieClip("mcSection", 0);
this.mcSection.moveTo(0, 0);
this.mcSection.attachMovie("productSlideshow", "mcProductSlideshow", 1, {_x:0, _y:30});
this.mcSection.createTextField("tDescription", 0, 160, 40, 230, 150);
this.mcSection.tDescription.multiline = true;
this.mcSection.tDescription.html = true;
this.mcSection.tDescription.wordWrap = true;
this.mcSection.tDescription.htmlText = sDescription;
}
function displayAdvantages():Void {
this.mcSection.removeMovieClip();
this.createEmptyMovieClip("mcSection", 0);
this.mcSection.moveTo(0, 0);
this.mcSection.attachMovie("advantages_box", "mcAdvantages_box", 1, {_x:50, _y:50});
this.mcSection.mcAdvantages_box.advantages.htmlTex t = sAdvantages;
}
function displaySpecs():Void {
this.mcSection.removeMovieClip();
this.createEmptyMovieClip("mcSection", 0);
this.mcSection.moveTo(0, 0);
this.section.attachMovie("specs_table", "mcSpecs_table", 1, {_x:10, _y:50});
this.mcSection.mcSpecs_table.tAnmischverhaeltnis.h tmlText = aSpecs['anmischverhaeltnis'];
// ...
this.mcSection.mcSpecs_table.tAbbindeexpansion.htm lText = aSpecs['abbindeexpansion'];
}

always refer to global members using the _global identifier, then it's certain to work.

[compuboy1010]

But I am using the _global identifier. See the first few lines of the script.

I am a beginner. Sorry, could you please be more specific and give me an example using my code? Isn't the "_" identifier only used for class variables?

Also, should the event handlers


// event handlers for product info MCs
_level0.main.mcProduct.mcAdvantages.onRelease = function() {
_level0.main.mcProduct.displayAdvantages();
};


etc

be outside the tree listener? I am confused.

[creynders]

I meant to use the _global identifier not only when initializing the variable (=setting it's value) but also when refering (/using) the variable.
code snippet:
if (bSuccess) {
_global.bLoadedOK = true;
var xnRoot:XMLNode = this.firstChild;
var xnProductName:XMLNode = xnRoot.firstChild;

[compuboy1010]

Is it mandatory or only for the purpose of being easier to read?

[creynders]

it's easier to read, and then you know for certain where the compiler is gonna go look for the variables (so yes make that mandatory)

[compuboy1010]

Thank you very much!!! You saved my life!

Can I ask a last question? It is driving me nuts ...

Why is this line only excecuted in the event handler and not right after the "delete this.onEnterFrame" ?????? Strange as hell.
