Program 21.2 Can't Connect Buttons

[diggerbyte]

Help!  I can't get the digit buttons to connect to my click digit: method.  What am I doing wrong? It was easy in 21.1.  Is this the correct .xib file?

    int               currentNumber;
    NSMutableString   *displayString;
    BOOL              firstOperand, isNumber;
    Calculator        *myCalculator;
}

A .xib (or nib) file to us is not a file of code.  It is a graphical representation of a view.

I am not quite sure what you have done here.
