function lookUpProfile(name, prop){
// Only change code below this line
for (var i=0;i<contacts.length;i++){
  if (contacts[i].firstName==firstName){
    if (contacts[i].hasOwnProperty(prop)){
      return contacts[i][prop];
    }else{
      return "No such property";
    }
  }
}
    return "No such contact";
  
// Only change code above this line

hi @Wood-Cube

Its this line here:

if (contacts[i].firstName==firstName)

try replacing with:

if (contacts[i].firstName==name)

You want to be comparing the firstName value in the array with the name value brought in by the function, not itself.

Let me know how it goes!
