Signing Up New Users Part 3/4 Code Challenge

"If the guess is correct, we want to alert the user with a message using a UIAlertView. Add an if statement that checks if the BOOL variable 'isCorrect' is true (or 'YES'). Inside the if statement, declare a new UIAlertView variable named 'alertView'. Alloc/init it with the method 'initWithTitle:message:delegate:cancelButtonTitle:otherButtonTitles'. For the title, use "Hooray!", for the message, use "You did it!", for the delegate use nil, for cancelButtonTitle use "OK", and for otherButtonTitles use nil."

#import "NumberGuesserViewController.h"
#import "GuessEngine.h"
#import "UIAlertView.h"

@implementation NumberGuesserViewController

- (IBAction)makeGuess:(id)sender {
    NSString *userNumber =self.numberField.text;

    if (isCorrect == YES){ UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Hooray!" message:@"You did it!" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil]; }


    // Check to see if the user's number is correct
    BOOL isCorrect = [GuessEngine testGuess:userNumber];
}

@end

What is wrong with my code? tnx

You may want to move the BOOL outside of the makeGuess method.

You also should have [alertView show]; in the if statement.
