Simple Calculator AS3 class: Can't figure out how to referance input text box string

programming flash
1

Hello,
I’ve decided that in my attempts to learn flash, I had started, well, to big… so, I’ve went back to the basics and have started working on learning how to make a simple AS3 class.

I’ve made a simple calculator application that allows you to add, subtract, multiply, and divide after entering 2 values into their respective text box.

The problem, how ever, is once I moved it into it’s own class, I cannot figure out how to reference the text fields. I have the movie clips referenced just fine, but, I cannot figure out the text fields.

Here are the errors it’s spitting out:

1120: Access of undefined property Number1_txt.
1120: Access of undefined property Number2_txt.
1120: Access of undefined property finalValue_txt.

And it does that for each instance of those in the Calculator.as

Main.as

package {
import flash.display.MovieClip;
    public class Main extends MovieClip {
        
        public var plus_btn:MovieClip;
        public var minus_btn:MovieClip;
        public var mult_btn:MovieClip;
        public var div_btn:MovieClip;
        public var urlLINK_btn:MovieClip;
        public var Number1_txt:String;
        public var Number2_txt:String;
        public var finalValue_txt:String;
        
        public function Main() {
            
            var calculator:Calculator = new Calculator(plus_btn, minus_btn, mult_btn, div_btn, urlLINK_btn, Number1_txt, Number2_txt, finalValue_txt);
            
        }
        
    }
}

Calculator.as

package {

    import com.plagro.loaders.getURL;
    import flash.display.MovieClip;
    import flash.events.Event;
    import flash.events.MouseEvent;

    public class Calculator extends MovieClip {

        public var finalValue:Number;

        public function Calculator(plus_btn:MovieClip, minus_btn:MovieClip, mult_btn:MovieClip, div_btn:MovieClip, urlLINK_btn:MovieClip, Number1_txt:String, Number2_txt:String, finalValue_txt:String) { //ADD IDENTIFIERS HERE TO MAKE IT MORE DYNAMICS

            plus_btn.buttonMode = true;
            minus_btn.buttonMode = true;
            mult_btn.buttonMode = true;
            div_btn.buttonMode = true;
            urlLINK_btn.buttonMode = true;

            plus_btn.addEventListener(MouseEvent.CLICK, plusClick);
            minus_btn.addEventListener(MouseEvent.CLICK, minusClick);
            mult_btn.addEventListener(MouseEvent.CLICK, multClick);
            div_btn.addEventListener(MouseEvent.CLICK, divClick);
            urlLINK_btn.addEventListener(MouseEvent.CLICK, URLClick);

        }

        function plusClick(e:Event) {
            var value1:Number = Number(Number1_txt.text);
            var value2:Number = Number(Number2_txt.text);

            finalValue = value1 + value2;

            finalValue_txt.text = String(finalValue);
        }

        function minusClick(e:Event) {
            var value1:Number = Number(Number1_txt.text);
            var value2:Number = Number(Number2_txt.text);

            finalValue = value1 - value2;

            finalValue_txt.text = String(finalValue);
        }

        function multClick(e:Event) {
            var value1:Number = Number(Number1_txt.text);
            var value2:Number = Number(Number2_txt.text);

            finalValue = value1 * value2;

            finalValue_txt.text = String(finalValue);
        }

        function divClick(e:Event) {
            var value1:Number = Number(Number1_txt.text);
            var value2:Number = Number(Number2_txt.text);

            finalValue = value1 / value2;

            finalValue_txt.text = String(finalValue);
        }

        function URLClick(e:Event) {
            new getURL("http://www.url.com/");
        }


    }
}

Any help will be greatly appreciated.

Thanks in advance,
