I have tried NSString *userNumber = self.numberField.text it doesnt work idk why

I have tried NSString *userNumber = self.numberField.text it does not work and then i also added all the methods from the previous video and that did not work either. Why does this not work??

NumberGuesserViewController.h 
#import "UIViewController.h"
#import "UITextField.h"

@interface NumberGuesserViewController : UIViewController

@property(strong,nonatomic)IBOutlet UITextField *numberField;

- (IBAction)makeGuess:(id)sender;

@end
NumberGuesserViewController.m 
#import "NumberGuesserViewController.h"
#import "GuessEngine.h"
#import "UIAlertView.h"

@implementation NumberGuesserViewController

- (IBAction)makeGuess:(id)sender {
    NSString *userNumber;
NSString *userNumber = self.numberField.text;
    // Check to see if the user's number is correct
    BOOL isCorrect = [GuessEngine testGuess:userNumber];


@end

You are double typing your "userNumber" variable.

Change 

NSString *userNumber = self.numberField.text;

to

userNumber = self.numberField.text;
