Javascript not working in TextWrangler

Question

This is a color guessing game. However when I try to run it from TextWrangler nothing happens. But when I use a javascript editor online the game works perfectly. Is there something wrong with my code or is there a problem with TextWrangler???

    var finished = false;
    var guess = 1;
    var colors=["blue","yellow","red","green","brown","black"];
    colors= colors.sort();      

    function do_game () {

        var random_number = (Math.random() * (colors.length-0)) + 0;
        var random_number_integer = Math.floor(random_number);
        target_index= random_number_integer;
        var target = String(colors[random_number_integer]);
        alert("" + target);     

        while (!finished) {
          guess_input_text = prompt("I am thinking of one of these colors: \n\n" +
                                colors.join(",") + "\n\n What color am I thinking of?");

          guess_input = colors.indexOf(guess_input_text);
          guess += 1;
