Everything looks fine, but with my code, I cannot find the person and I do not know why

A. The code of search_report.js on js folder: var keyword;

while(true) { keyword = prompt('Please type the name of the person you are looking for'); if(keyword === 'quit'){ break;

} else {
    if(find_figure(keyword)){
        var message = print_figure(keyword); 
        print(message); 

    } else {
        keyword = prompt('Who you are looking for is not available in our database, please try                again'); 
    }

}

}

function find_figure(keyword){ for(var i = 0; i< students.length; i +=1){ if(keyword === students[i].name){ return true;

    }

}
return false; 

}

function print_figure(keyword){ var message = ''; message += '<h2>Name: ' + keyword.name + '</h2>'; message += '<p>Track: ' + keyword.track + '</p>'; message += '<p>Achievements: ' + keyword.achievements + '</p>'; message += '<p>Points: ' + keyword.points + '</p>'; return message;

}

function print(message){ var div = document.getElementById('output'); div.innerHTML = message;

}

B. The code of students.js on js folder: var students = [ { name: 'Dave', track: 'Front End Development', achievements: 158, points: 14730 }, { name: 'Jody', track: 'iOS Development with Swift', achievements: '175', points: '16375' }, { name: 'Jordan', track: 'PHP Development', achievements: '55', points: '2025' }, { name: 'John', track: 'Learn WordPress', achievements: '40', points: '1950' }, { name: 'Trish', track: 'Rails Development', achievements: '5', points: '350' } ];

C. The code of student_report.js on js folder: var message = ''; var student;

function print(message) { var outputDiv = document.getElementById('output'); outputDiv.innerHTML = message; }

for (var i = 0; i < students.length; i += 1) { student = students[i]; message += '<h2>Student: ' + student.name + '</h2>'; message += '<p>Track: ' + student.track + '</p>'; message += '<p>Points: ' + student.points + '</p>'; message += '<p>Achievements: ' + student.achievements + '</p>'; }

Above are all of the codes I have for the challenge in js folder, I ran the code but I cannot search the person I want. Could anyone please help me look for mistakes I made? Thank you. Help would be appreciated.

The function "print_figure" is defined to take a "keyword" argument, and when it is called a string is passed to it. But it attempts to access properties that a string would not have. It seems obvious that one of the objects from the "students" array should be passed to it instead.

The function that identifies the record only returns a true/false condition, so a good bit of logic re-design will be needed to display the record that matches the search term.
