There's something wrong with this challenge. BUMMER IT'S NOT WORKING!

I've tried changing my code to answer the question, but it's not working for some reason. I know it's got to be right. Can someone help me please? I don't know what I did wrong.

Hello Roxanne!

Sorry to hear you're having trouble. I'd love to try and help. Can you provide your code so I can look it over and try to recreate the problem?

CREATE TABLE MEMBERS(ID INT PRIMARY KEY, FIRST_NAME VARCHAR(255), LAST_NAME VARCHAR(255), FAVORITE_ROCK_ID REFERENCES ROCK(ID));

I still have this error coming up saying I need a foreign key constraint.

Hi Roxanne!

(The Police is my favorite band, so kudos on the cooooool name!)

This passes the first challenge:

CREATE TABLE ROCKS (
    ID NOT NULL UNIQUE PRIMARY KEY,
    NAME,
    TYPE,
    COLOR
  );

This passes the second:

DROP TABLE MEMBERS;

This passes the third:

CREATE TABLE MEMBERS (
     ID NOT NULL UNIQUE PRIMARY KEY,
     FIRST_NAME,
     LAST_NAME,
     FAVORITE_ROCK_ID REFERENCES ROCKS(ID)
 );

(And yes, even though they pass, there are still some weird error messages, but I don't understand why they are generated!?!)

I hope that helps.

Stay safe and happy coding!

Hi Peter Vann! Thanks for your help. I finally figured out the problem and solved the challenge. And yes the Police is an awesome band and they happened to have a cool song named after me. Every time I meet someone new they always end up singing that song to me. LOL
