Schedules greyed out

My brother in law worked outside India during last financial year.

He earned 

1. salary outside India,
2. interest from savings account in India
3. some variable pay from his last job in India, received after some months without deducting tds.
4. nothing else, no capital gains etc.

I selected ITR2.

a. I have to show his salary earned outside India in schedule FA. I hope this is right. But this schedule is greyed out.

b. I am not sure how to enter the variable pay?

Thanks
