challenge 3/4 of Signing Up New users part 2, I am getting an error in my code and am lost as to why!

QUESTION: Now let's use the 'signUpInBackgroundWithBlock' method to sign up this new user. Send this message to the newUser variable. For the block parameter, copy and paste the following empty block: ^(BOOL succeeded, NSError *error) {}

ANSWER: [newUser signUpInBackgroundWithBlock:^(BOOL succeeded, NSError *error) { if (error) { UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Sorry!" message:[error.userInfo objectForKey:@"error"] delegate:nil cancelButtonTitle:@"OK" otherButtonTitles: nil]; [alertView show]; }];

The task states: or the block parameter, copy and paste the following empty block: ^(BOOL succeeded, NSError *error) {} so the block needs to be empty, you put code inside the block. remove it so that its empty:

- (IBAction)signup:(id)sender {

    self.username = self.usernameField.text;
    self.password = self.passwordField.text;

    PFUser *newUser = [PFUser user];
    newUser.username = self.username;
    newUser.password = self.password;

    [newUser signUpInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {

    }];
}
