Thank you Roge1722 and Irene2805. You are correct roger, no entry in box 2 and 3. So just to be clear, in first k1 i put values of code a, b, f, m and p. in the 2nd k1 i will fill out section 1, can skip section 2 and in section 3 i just do box 16 and put values of code a, g and n but nothing else. Is that correct?
