Argument error 1063 in AS3 - actionscript-3

Question

so I have been working on a game called rock scissors paper lizard spock.
I got this error:
ArgumentError: Error #1063: Argument count mismatch on FlashGame_fla::MainTimeline/backtoBanana(). Expected 0, got 1.
this is my main code:
import flash.display.MovieClip;
import flash.events.MouseEvent;
import flash.text.TextFormat;
rulesButton.addEventListener(MouseEvent.CLICK, toggleRule);
gameRules.addEventListener(MouseEvent.CLICK, toggleRule);
gameRules.visible = false;
gameRules.buttonMode = true;
function toggleRule(evt:MouseEvent):void
{
gameRules.visible = ! gameRules.visible;
}
menuButton.addEventListener(MouseEvent.CLICK, Click_backtoMain);
function Click_backtoMain(event:MouseEvent):void
{
gotoAndStop(213);
}
var isRolling:Boolean = false; //defalt is "false"
var pDieVal:int = 0;
var gDieVal:int = 0;
var pScore:int = 0;
var gScore:int = 0;
var pRolls:int = 0;
pDieMC.stop();
gDieMC.stop();
msgDisplay.text = "Click on the banana \nbutton to roll the die!";
pScoreDisplay.text = "0";
gScoreDisplay.text = "0";
rollButton.addEventListener(MouseEvent.CLICK, rollDie);
rollButton.addEventListener(MouseEvent.CLICK, dieRoll);
bananaWinLose.visible = false;
gameOverBananaMC.visible = false;
toMenuBtn.visible = false;
rollAgainBtn.visible = false;
function rollDie(evt:MouseEvent): void
{
if (isRolling)
{
//change flag to show die is NOT rolling
isRolling = false;
//change the label on the button to "BANANA!"
buttonDisplay.text = "BANANA!";
// STOP the dice animations
pDieVal= Math.ceil(Math.random() * pDieMC.totalFrames);
pDieMC.gotoAndStop(pDieVal);
gDieVal = Math.ceil(Math.random() * gDieMC.totalFrames);
gDieMC.gotoAndStop(gDieVal);
//set message display to an empty string
msgDisplay.text = "";
whoWon();
score();
}
else
{
//change flag to show die is rolling
isRolling = true;
//change the label on the button to "Stop"
buttonDisplay.text = "POPADAM!";

}
}
function whoWon():void
{
// is it a tie?
if (pDieVal == gDieVal)
{
msgDisplay.text = "Papoi?! It's a tie!";
}
else
{
// assume the player has lost
var hasPlayerWon:Boolean = false;
// determine if the player wins
if (pDieVal == 1 && (gDieVal == 4 || gDieVal == 5))
{
hasPlayerWon = true;
}
else if (pDieVal == 2 && (gDieVal == 1 || gDieVal == 5))
{
hasPlayerWon = true;
}
else if (pDieVal == 3 && (gDieVal == 1 || gDieVal == 2))
{
hasPlayerWon = true;
}
else if (pDieVal == 4 && (gDieVal == 3 || gDieVal == 2))
{
hasPlayerWon = true;
}
else if (pDieVal == 5 && (gDieVal == 3 || gDieVal == 4))
{
hasPlayerWon = true;
}
// display the results to the player
if (hasPlayerWon)
{
msgDisplay.text = "Yay! You win!";
}
else
{
msgDisplay.text = "Boo! Stuart wins!";
}
}
}
function dieRoll(evt:MouseEvent):void
{
trace("calculating pRolls");
if (pRolls == 20)
{
rpslsWon();
}
else
{
//increment pRolls by 1
pRolls++;
}
}
function score():void
{
//if player wins, his/her score increases by 1
if (msgDisplay.text == "Yay! You win!")
{
pScore = pScore + 1
pScoreDisplay.text = pScore.toString();
//if player loses, computer score increases by 1
}
else if (msgDisplay.text == "Boo! Stuart wins!")
{
gScore = gScore + 1
gScoreDisplay.text = gScore.toString();
//if neither wins, their scores remain unchange
}
else
{
pScore = pScore
gScore = gScore
}
}
function rpslsWon():void
{
gameOverBananaMC.visible = true;
bananaWinLose.visible = true;
bananaWinLose.text = "Kampai! You are totally bananas!! \nYour Score: " + pScore;
toMenuBtn.visible = true;
rollAgainBtn.visible = true;
toMenuBtn.addEventListener(MouseEvent.CLICK, Click_backtoMain);
rollAgainBtn.addEventListener(MouseEvent.CLICK, backtoBanana);
}
function backtoBanana():void
{
pScore = 0;
gotoAndStop("menu");
gotoAndStop("banana");
}
so the error appears in the function backtoBanana(), I can't seem to fix it.
Can someone help me? Thanks alot.

Answer 1

The callback function for the MouseEvent-listener will be passed a MouseEvent. Change
function backtoBanana():void
to
function backtoBanana(event:MouseEvent):void
just like your other callback function:
function Click_backtoMain(event:MouseEvent):void
