Stage 2 --- Error Messages with Dialogs

Hi , i have a question about the code challenge 2/5. The objective is to set the mUserInput using the text value from mNumberField.

public class GuessNumberActivity extends Activity {

protected String mUserInput;
protected EditText mNumberField;

/*
 * onCreate() and other code has been omitted for brevity!
 */

public void makeGuess() {
    // Set mUserInput here!        
      mUserInput = (EditText)findViewbyId(R.id.****);
    // Check to see if the user's number is correct
    boolean isCorrect = GuessEngine.testGuess(mUserInput);

}

}

What should i put in the findViewById or this is not the way to set it? Thanks.

It is a bit unclear but the description states that the view is declared in the onCreate method. What you should type is mUserInput = mNumberField. getText().toString();

This assigns the user input the numberfield value by using the getText method, you also need to add toString at the end to convert the value to a string to match the variable type.
