A question About ELSE

[rocketscreen]

if (_x < eval("/:x") + 40 && eval("/:x") - 40 < _x && eval("/:crash") == 0)
{
    if (eval("/:jump") > 0 && mode > 0)
    {
        /:bonus = 5;
    }
    else if (mode = 2)
    {
        tellTarget("/lives")
        {
            /:lives = eval("/lives") + 1;
            prevFrame ();
            tellTarget("")
            {
                tellTarget("/sound")
                {
                    gotoAndStop("bonus");
                    tellTarget("")
                    {
                        tellTarget("/" add hazard add "a")
                        {
                            gotoAndStop(1);
                            tellTarget("")
                            {
                                gotoAndStop(1);
                            }
                        }
                    }
                }
                else
                {
                    /:crash = 1;
                    setProperty("/crash", _x, getProperty("/player", _x));
                    setProperty("/crash", _x, getProperty("/player", _x));
                    setProperty("/crash", _rotation, getProperty("/player", _rotation));
                    tellTarget("/crash")
                    {
                        gotoAndPlay(2)
                        tellTarget("")
                        {
                            tellTarget("/player/character")
                            {
                                gotoAndStop(3);
                                tellTarget("")
                                {
                                    tellTarget("/lives")
                                    {
                                        /:lives = eval("/lives") - 1;
                                        nextFrame();
                                        tellTarget("")
                                        {
                                            /:jump = 0;
                                        }
                                    }
                                }
                            }
                        }
                    }
                }
            }
        }
    }
} 

I used the above coding for a game that I'm currently making, but I get an ActionScript error saying that the else statement does not have a matching IF statement.. What do I do now?

Please help!
