Change Dynamic Text Color Using Actionscript

I am using Flash 8 and I am building a flash stock ticker. I want to change the color of the text based on change of the stock (positive or negative). I have created a text file using aspx and I am loading the variables from that file (here's the sample output):

sym_0=ABP&trade_0=4.24&sign_0=0&change_0=-0.16&percent_0=-3.64&name_0=ABRAXAS PETRO (N&sym_1=AGII&trade_1=31.81&sign_1=0&change_1=-0.12&percent_1=-0.38&name_1=ARGONAUT GROUP IN&sym_2=ALG&trade_2=21.27&sign_2=0&change_2=-0.06&percent_2=-0.28&name_2=ALAMO GP INC&sym_3=CFR&trade_3=56.00&sign_3=0&change_3=-0.10&percent_3=-0.18&name_3=CULLEN FROST BNKR

I created a variable (sign_*) that denotes the change (0 = negative change, 1 = positive change).

Here's the code I have on my actions line of the movie, frame 1:

myData = new LoadVars();
myData.onLoad = function(){
   quote__0 = this.sym_0 + ": $" + this.trade_0 + ", " + this.change_0 + ", " + this.percent_0 + "% ";
   quote__1 = this.sym_1 + ": $" + this.trade_1 + ", " + this.change_1 + ", " + this.percent_1 + "% ";
   quote__2 = this.sym_2 + ": $" + this.trade_2 + ", " + this.change_2 + ", " + this.percent_2 + "% ";
   quote__3 = this.sym_3 + ": $" + this.trade_3 + ", " + this.change_3 + ", " + this.percent_3 + "% ";
   
               format = new TextFormat();
            format.color = 0x00FF00;
            
         if (this.sign_0 == 1) {
            tQuote_0.setTextFormat(format);
            };
       if (this.sign_1 == 1) {
            tQuote_1.setTextFormat(format);
            };
            if (this.sign_2 == 1) {
            tQuote_2.setTextFormat(format);
            };
            if (Number(this.sign_3) == 1) {
            tQuote_3.setTextFormat(format);
            };

};

myData.load("../stocks.txt");


All of the dynamic text boxes individual graphics, instances are given for each text box).
Everything works except changing the color of the font.

HELP!
