I get a "Nan" error on score counter to when player has choose level from menu

Question

I made a score counter and if has player start level 1 and if has win,counter is keep working to next level.( Level = frame ) it's not exist any issue so far.

But when player has choice to level from menu and start level 2,counter is not work.Level 2 start from to frame 116.I get a "NaN" error.

I write a code like this scrore frame 1

var Scorecounter:Number = 0;

And Score_t1 it's a dynamic text.Use counter code on frame one

function checkButtonsone():void
{
    if(fisoneclicked21 && fistwoclicked)
    {

    Scorecounter = Scorecounter + 10;
    Score_t1.text = (Scorecounter).toString();

    acmessage.visible = true;
    acmessage.play();

    gotoAndPlay(116);//LEVEL 2
}
}

and on level 2

function checkButtonponelev2():void
{
    if(fish1clickedleveltwo && fishtwoclickedleveltwo && 
    fishthreeclickedleveltwo)

    {           
    Scorecounter = Scorecounter + 10;
    Score_t1.text = (Scorecounter).toString();

    famessage.visible = true;
    famessage.play();
}
}

I'm not using keyframe beetwen two levels.So score frame continue until last frame.(285)

Well, I've no idea why timeline scripting not working for you (you might want to trace Scorecounter if it inits though), but I can suggest a "global" variable solution. Create a class file ScoreHolder.as and put it in the same folder as your *.fla

package
{
    public class ScoreHolder
    {
        static public var score:Number = 0;
    }
}

Then import it in any frame where you want to access the score value:

import ScoreHolder;

function checkButtonsone():void
{
    if (fisoneclicked21 && fistwoclicked)
    {
        ScoreHolder.score += 10;
        Score_t1.text = ScoreHolder.score.toString();

        acmessage.visible = true;
        acmessage.play();

        gotoAndPlay(116);//LEVEL 2
    }
}
