code challenge 3 of 3, symbol error

Hello I'm on challenge 3 but it gives me complie error, I don't know what is wrong here

com/example/model/Course.java 
package com.example.model;

import java.util.List;

public class Course {
  private String mName;
  private List<Video> mVideos; 

  public Course(String name, List<Video> videos) {
    mName = name;
    mVideos = videos;
  }

  public String getName() {
    return mName;
  }

  public List<Video> getVideos() {
    return mVideos;
  }

}
com/example/model/Video.java 
package com.example.model;

public class Video {
  private String mTitle;

  public Video(String title) {
    mTitle = title;
  }

  public String getTitle() {
    return mTitle;
  }

  public void setTitle(String title) {
    mTitle = title;
  }

}
QuickFix.java 
import com.example.model.Course;
import com.example.model.Video;

import java.util.Map;
import java.util.TreeMap;

public class QuickFix {

  public void addForgottenVideo(Course course) {
   Video video = new Video("The beginning bits");
    course.getVideos().add(1, video);

  }

  public void fixVideoTitle(Course course, String oldTitle, String newTitle) {
    Map<String, video> videos = new TreeMap<>();
    videos = videosByTitle(course);
    videos.get(oldTitle).setTitle(newTitle);

  }

  public Map<String, Video> videosByTitle(Course course) {
    Map<String, Video> VideoMap = new TreeMap<>();
    for (Video video: course.getVideos()) {
      VideoMap.put(video.getTitle(), video);
    }
    return VideoMap;
  }

}

Edit: nvm, I figured it out, I didn't capitalize the Video in Map<>.
