Hi,
I’m pulling my hair out!
Can someone please help?
I’m working on a puzzle game.
At present, when all the pieces are put in place it takes you to a specific frame.
However I want to be able to go to 1 of 2 screens depending on the time the puzzle has been completed. I’ve added the code below.
Below I have code for a timer

//if (Hours==0 && Minutes==0 && Seconds==0){
if (Minutes==0 && Seconds==0){
   gotoAndPlay(13);
}
else {
if (Seconds>0){
        Seconds--;
    }
    else {
         if (Minutes>0) {Minutes--; Seconds=59;}
         else {
         //Hours--;
         Minutes=59;
         Seconds=59;
         }
    }
if (Seconds<10){
//    Timer=Hours+":"+Minutes+":0"+Seconds;
 Timer=Minutes +":0"+ Seconds;
    } else if(Minutes<10){
         //Timer=Hours+":0"+Minutes+":"+Seconds;
   Timer="0"+ Minutes +":"+ Seconds;
      //}     else Timer=Hours+":"+Minutes+":"+Seconds;
   }     else Timer=Minutes+":"+Seconds;
    
//if (Hours>=0 && Minutes>=0 && Seconds>=0) gotoAndPlay(2);
if (Minutes>=0 && Seconds>=0) gotoAndPlay(2);
var TimerA,sisaMin,sisaSec;
if (Seconds>30){
 sisaSec = 90 - Seconds;
 sisaMin = 1 - Minutes;
} else if (Seconds<30) {
 sisaSec = 30 - Seconds;
 sisaMin = 2 - Minutes;
}
if (sisaSec<10){
 TimerA=sisaMin +":0"+ sisaSec;
    } else if(sisaMin<3){
   TimerA="0"+ sisaMin +":"+ sisaSec;
   //TimerA=sisaMin +":"+ sisaSec;
   }     else TimerA=sisaMin+":"+sisaSec;
  _root.disp_time_2="Well done, 20 points in " + TimerA + " min:sec.";
}
 if (sisaMin==0){
  _root.disp_time_2="Awesome, 20 points in less than 1 minute";
}

Below is the code i have for a puzzle piece

on (press) {
 startDrag(this, true);
}
on (release) {
 stopDrag();
 if (this._droptarget == "/box9") {
  _root.corSound.start();
  _root.count = _root.count+1;
  _root.cnt = _root.count;
  this._visible = false;
  tellTarget ("/box9") {
   gotoAndStop("pic");
   _alpha = 100;
  }
  if (_root.count >= 10) {
   tellTarget ("/") {
    _root.gotoAndStop(4);
    zwee111.start();
   }
  }
 } else {
  _root.wrSound.start();
 }
}

Thanks
