One class function can't fire another?

1

I’m starting to learn classes and I’m doing a class that loads a textfile with a variable, using loadVars, followed by pure html text, then it applies css to the html text and displays it in a target textfield…
I’m still new at this as I said so the code is very rough. I’ve worked out all the little kinks up to now… I’m stuck at one thing:
When the text loads, the “loadVars.onLoad = function” is supposed to fire the css function that applies the stylesheet to the text, but I simply can’t get the function to run…
Is it impossible to call a private function from another private function in a class block?

code:


class LoadHtmlText {
    /**
                    * LoadHtmlText Constructor
                    *
                    * @param    url            The path to the textfile
                    * @param    textFileVar    The variable name in the textfile
                    * @param    target        The TextField instance
                    *                        that will display the text
                    * @param    CSSurl        The path to a CSS file
                    */
    private var loadText:LoadVars;
    private var cssStyle:TextField.StyleSheet;
    public function LoadHtmlText(url:String, textFileVar, target:TextField, CSSurl:String) {
        newLoadVars();
        newStyleObject();
        textLoader(url, target, CSSurl, textFileVar);
        
        //CSSLoader(CSSurl, target);
    }
    // newLoadVars
    private function newLoadVars() {
        loadText = new LoadVars();
    }
    private function newStyleObject() {
        cssStyle = new TextField.StyleSheet();
    }
    // load some text
    private function textLoader(url:String, target:TextField, CSSurl:String, textFileVar) {
        loadText.load(url);
        // check if loaded:
        loadText.onLoad = function(success) {
            if (success)
            {
                trace("text loaded");
                CSSLoader(CSSurl, target, textFileVar);
                
            }
            else
            {
                trace("text not loaded");
            }
            
        };
    }
    // load a css
    private function CSSLoader(CSSurl:String, target:TextField, textFileVar) {
        trace("css function ran");
        cssStyle.load(CSSurl);
        cssStyle.onLoad = function(success) {
            if (success)
            {
                trace("css loaded");
                target.html = true;
                target.multiline = true;
                target.wordWrap = true;
                target.styleSheet = cssStyle;
                target.htmlText = loadText[textFileVar];
                trace(this);
            }
            else
            {
                trace("css not loaded");
            }
        };
//return target;
    }
}

Any help is highly appreciated!
