Countdown timer expression error

[defaultj871vzs5wsne]

I'm trying to make a countdown timer from text, counting down from 10 minutes. I'm using an expression on a Slider Control that has always worked but it seems like it doesn't work with the latest update.

This is the expression I'm using: 

slider = Math.round(effect("Slider Control")("Slider"))      

sec = slider%60 

min = Math.floor(slider/60) 

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

addZero(min) + ":" + addZero(sec)

I got the error on line 4:'' Error; SyntaxError; Unexpected 'else'

If anyone has any suggestions I would really appraciate the help!

Sloppy expressions are no longer acceptable. Your if()else{} statement needs to be properly encased/ terminated with curly brackets. Reformatting also helps to detect such errors:

slider = Math.round(effect("Slider Control")("Slider"))      

sec = slider%60 
min = Math.floor(slider/60) 

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

addZero(min) + ":" + addZero(sec)
