Code Challenege: Signing Up New Users Part 1 Help

What is wrong with this code that it's not allowing me to pass the second part (This is the task: In the 'makeGuess' method, store the text value from 'numberField' in the variable named 'userNumber'.)

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

This is the exact thing we learned in the past video.

I'm not an expert but maybe remove the [ ] around self.numberfield.text ? May be you can copy the error you get from xcode ?

Yep, I agree with Gregory, just trying to remove square brackets. The square brackets are used when you have to call a method. When you have to access values of a property, like in this case, the brackets are not necessary :)

did that work for you? i ended up doing this and passed that task of the code challenge but now i am having problems on the third part.

I cant figure out how to add the if statement that checks if the BOOL variable isCorrect is true here is what my code looks like 

if (isCorrect == Yes){

    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Hooray!" message:@"You did it!"
    delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil];
    }

i think the alert view is all good its just the first part i am worries about....
