you're missing a + sign prior to mAuthor in the toString method. It also requires use of the override tag.

try

    @Override
    public String toString(){ 
      return "BlogPost: "+mTitle + " by "+ mAuthor;
    }

Hey Harrison,

This is a great challenge so I don't want to just give the answer, however I'll give you some help. There is a very useful way to Format Strings without concatenation or calling an IO device.

It's showed below.

String.format("");

We can use this method just like it was a printf method, meaning that pass in place holders and plug in values.

So really, our answer would begin with

@Override 
public String toString() {
Return String.format(" // hmmmm I need to pass in the string and add in values like the title and mAuthor method, I wonder if we have methods that return those in this class? "))

Thanks, I hope this helps.
