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