1084:Syntax error:expecting rightparen before "true"

Hi, Im fairly new to actionscript and im actually following a pdf my lecturer sent me. After checking my codes repeatedly i cant seem to find where the errors come from. Here is my codes

package com.josephlabrecque {

import flash.display.MovieClip;
import flash.text.TextField;
import flash.display.SimpleButton;
import flash.events.Event;
import com.josephlabrecque.QuestionBank;
import flash.events.MouseEvent;
import flash.utils.setTimeout;


public class QuizGame extends MovieClip {

public var trueBtn: SimpleButton;
public var falseBtn: SimpleButton;
public var questionText:TextField;
public var statusMsg:TextField;

private var questionBank:QuestionBank;
private var questionArray:Array;
private const questionMax:int = 5;
private var questionCount:int = 0;
private var currentAnswer:String;
private var currentScore:int = 0;

public function QuizGame() {
statusMsg.text = "";
questionArray = new Array();
questionBank = new QuestionBank();
questionBank.addEventListener(Event.COMPLETE,dataReady);
trueBtn.addEventListener(MouseEvent.CLICK, truePressed);
falsBtn.addEventListener(MouseEvent.CLICK, falsePressed);
}

private function truePressed(e:MouseEvent):void {
if(statusMsg.text == ""){
if(currentAnswer -- "true"){
curruntScore += 100/questionMax;
statusMsg.text = "CORRECT"
}else{
statusMsg.text = "WRONG";
}
setTimeout(newQuestion, 1000);
}
}

private function falsePressed(e:MouseEvent):void {
if(statusMsg.text == ""){
if(currentAnswer -- "false"){
curruntScore += 100/questionMax;
statusMsg.text = "CORRECT"
}else{
statusMsg.text = "WRONG";
}
setTimeout(newQuestion, 1000);
}
}

private function dataReady(e:Event):void {
questionArray = questionBank.buildBank();
grabQuestion();
}

private function newQuestion ():void {
statusMsg.text = "";
trace(currentScore);
grabQuestion();
}

private function grabQuestion():void {
if(questionCount < questionMax){
var max:int = questionArray.length-1;
var rq:int = Math.floor(Math.random() * (max - 0 + 1));
var ta:Array = questionArray.splice(rq, 1);
questionText.text = ta[0].q;
currentAnswer = ta[0].tf;
questionCount++;
} else{
gameOver();
}
}

private function gameOver():void{
statusMsg.text = currentScore+"/100points";
questionText.text = "Game Over";
}
}
}

The red text is where im having the same syntax error (as mentioned in the subject field), ive been trying to rectify this for more than 2hr and still cant seem to find the soluction. Any help would be much appreciated. Thanks in advance.
