MATLAB simulink onramp 7.1 task 1

I was doing task 1 of 7.1 of simulink onramp and I couldn't understand this error. How to add object name ?

Please try relaunching the task .

Simulink Onramp 7.1 task 1 is to change the amplitude of sine wave block .

It can be done by double clicking on the sine block and in the amplitude field change 1 to r .

Then connect the signal to Signal Assessment and press Submit .

There is always Hint and See Solution that u can refer to incase if the task is difficult or facing errors.
