Do property values have to be the same? here's my code. 

var objects = [
  { one: "how many wheels on a bycicle", 
   two: 2
  },
  {one: "how many tires on a car", 
   two: 4
  }, 
  {one: "how many legs do inesects have", 
   two: 6
  }];
var correctAnswers = 0;


function print(message) {
  document.write(message);
}

for( i = 0; i< objects.length; i += 1) {
  prit = objects[i].one;
  prit1 = objects[i].two;
  response = prompt(prit);
  response =  parseInt(response);
  if (response === prit1) {
    correctAnswers += 1
  }
}


html = "You got  " + correctAnswers + "  right!!"
print(html)

at first I tried to create a for loop from the previous exercise

for( i = 0; i< objects.length; i += 1) {
  for(prop in objects) { 
    var map = prop;
    var prit = objects[i].map;
    document.write(prit);
  }
}

what's funny about this thing is that if I do document.write(map) the property values propegate, but it does not work for document.write(prit)

the goal is to loop through all values of different name.s

I think the correct syntax should be objects[i][map];

You are using prit instead of print, it should have to be: response = prompt(print);
