Hello!

if(contacts[i][name] === name && contacts[i].hasOwnProperty(prop))

You are comparing an array of “name” with “name”.
You however want to check if “name” is equal to one of the keys in the objects (like firstName). Remember how to access that key (hint: " . ")

You are returning “no such contact” for just one contact at the moment. You have to move the return statement outside the loop so it checks all of them.
