Not sure how to make a public field and set it to a string. I thought i understood it but now I don't.

After writing the code to mirror similarly to what the instructor in the video had written. I seem to be coming to an issue. Please help! This seems simple enough, but I am just confused because the challenge will only accept a certain code.

GoKart.java 
public class GoKart{
  public static void main(String[] args) {

  }
}

The question is:

Now let's temporarily add a public field that we will use to store the color of the GoKart. Let's make it the set to the String of "red".

You don't need that main method you added there.

I'll show you using another example.

JustAnExample.java 
public class JustAnExample {
     public String mAnExampleField = "an example value";
}

I did that exact code, proper variables of course and it prompted an error. I will try again and post code. Thanks Craig.

Craig! I just figured it out. I didn't fully understand what a member variable was till just now!

Instead of "... String color..."

I put "... String mColor = ..."

I agree the next challenge is... lol challenging. I re-watched the video a few times I know I am still missing something haven't been able to get past the challenge. I have tried the same code that Craig uses. However, no dice. I guess I am still having trouble understanding the full concepts of a constructor and with the above question.
