After Effects Expression Error

[Ghulam5E2E]

rateOfSpeed=1;
clockStartTime = thisComp.layer("TImer Duration").effect("Slider Control")("Slider")*3600;
ClockTimeNumber = Math.floor(clockStartTime-rateOfSpeed*time);

function addZero(n){
if(n<10) {return "0" + n}else{return n};
}

minutes = Math.floor(clockTimeNumber/60);
seconds = clockTimeNumber%60;

if (clockStartTime > 0 && time < clockStartTime) {
addZero(minutes) + “:” + addZero(seconds);
}
else
{“00:00”}

This is the code, I copied it from a video. And then customize it according to my need. But I am getting error in the following line of code "Syntax Error" reference code: addZero(minutes) + “:” + addZero(seconds);

Change the curly quotes around the colon to straight quotes.

What @Dan_Ebbers said - you have Rich Text quotes, and they need to be converted to regular quotes, singe or double.

if (clockStartTime > 0 && time < clockStartTime) {
	addZero(minutes) + ": " + addZero(seconds);
} else {
	"00: 00";
}
