for ( var i = 0; i < questions.lenght; i += 1) {

Should be

for ( var i = 0; i < questions.length; i += 1) {

You have simply misspelled length as far as I can tell. Easy mistake to make and hard to spot. These little errors always pop up in my coding and I have to take a break then come back to it before I finally spot what is going on.
