[SOLVED]mCreationDate cannot find symbol

Alright, now let's order the blog post's creation date chronologically, oldest first.

NOTE: The app where this class is being used ensures that no two blog posts are posted at the same time, so you do not need to worry about any edge cases.

I've looked at other forum posts of this similar code but at different stages in the course. I've tried exactly what they've done but yet still can't pass the challenge. Not understanding why stuck.mCreationDate cannot find symbol when passed into the compareTo argument when I'm still within the class with the private field. Any suggestion? Maybe a different approach, doesn't necessarily say I have to return this information, just order it.

com/example/BlogPost.java
package com.example;

import java.util.Date;

public class BlogPost implements Comparable {
  private String mAuthor;
  private String mTitle;
  private String mBody;
  private String mCategory;
  private Date mCreationDate;

  public BlogPost(String author, String title, String body, String category, Date creationDate) {
    mAuthor = author;
    mTitle = title;
    mBody = body;
    mCategory = category;
    mCreationDate = creationDate;
  }
  @Override
  public int compareTo(Object other) {
    Object stuck = (BlogPost) other;
    if(equals(other)) {
      return 0;
    }
    // WHERE I FOUND MY MISTAKEEEEEEE
    int dateCmp = mCreationDate.compareTo(stuck.mCreationDate);
    if (dateCmp == 0) {
       return dateCmp;
     }
     // THE DOUBLE RETURN STATEMENT SEEMS A BIT POINTLESS BUT IT WORKED.
       return dateCmp;
  }

  public String[] getWords() {
    return mBody.split("\\s+");
  }

  public String getAuthor() {
    return mAuthor;
  }

  public String getTitle() {
    return mTitle;
  }

  public String getBody() {
    return mBody;
  }

  public String getCategory() {
    return mCategory;
  }

  public Date getCreationDate() {
    return mCreationDate;
  }

}

The other return statement isn't pointless. It is there if dateCmp doesn't equal 0.
