Pretty sure cturhan did try jffry's code and that's why he wrote this code. The $ var on the page only returns the first instance that it matches so his code doesn't work.

A less efficient but shorter way is:

    var interval = setInterval(function(){
    	var links = document.querySelectorAll('#problems a');
    	for(var z =0; z< links.length; z++) {
    		$('#'+links[z].id).click();
    	}
    }, 1000);

Also he never called him stupid he simply informed him that it didn't work.
