these errors (27 of them) show up and my stop command wont work, whats wrong with my code?? i'm new to flash action script, and i used a youtube tutorial to create the buttons (knapp) i refere to.

here's my code

stop();

//knappane til dei forskjellige planetane

//solen
solenKnappen.addEventListener(MouseEvent.CLICK, goToSolen);

function goToSolen(event: MouseEvent);void {
this.gotoAndStop("solen")
}

//merkur
merkurKnappen.addEventListener(MouseEvent.CLICK, goToMerkur);

function goToMerkur(event: MouseEvent);void {
this.gotoAndStop("merkur")
}

//venus
venusKnappen.addEventListener(MouseEvent.CLICK, goToVenus);

function goToVenus(event: MouseEvent);void {
this.gotoAndStop("venus")
}

//jorden
jordenKnappen.addEventListener(MouseEvent.CLICK, goToJorden);

function goToJorden(event: MouseEvent);void {
this.gotoAndStop("jorden")
}

//mars
marsKnappen.addEventListener(MouseEvent.CLICK, goToMars);

function goToMars(event: MouseEvent);void {
this.gotoAndStop("mars")
}

//jupiter
jupiterKnappen.addEventListener(MouseEvent.CLICK, goToJupiter);

function goToJupiter(event: MouseEvent);void {
this.gotoAndStop("jupiter")
}

//saturn
saturnKnappen.addEventListener(MouseEvent.CLICK, goToSaturn);

function goToSaturn(event: MouseEvent);void {
this.gotoAndStop("saturn")
}

//uranus
uranusKnappen.addEventListener(MouseEvent.CLICK, goToUranus);

function goToUranus(event: MouseEvent);void {
this.gotoAndStop("uranus")
}

//neptun
neptunKnappen.addEventListener(MouseEvent.CLICK, goToNeptun);

function goToNeptun(event: MouseEvent);void {
this.gotoAndStop("neptun")

Answer 1

Your code's error is when using a semicolon ( ; ) to indicate the types of your functions instead of using a colon ( : ), so the code for your goToSolen() function, for example, should be like this :

function goToSolen(event: MouseEvent): void 
{
    this.gotoAndStop("solen");
}

And of course you should do that with all your functions.

Hope that can help.
