javascript - Yes, another clearInterval Issue -

I'm officially stuck. I can not get the stopTimer () function to work properly, any help would be welcomed. Thanks!

Html ('Requery in:' + Gin + 'seconds.');}, 1000); } $ ('#start'). Click (function () {startTimer ();}); $ ('# Stop'). Click (function () {stopTimer ();});
