Itr 2

Hi, I was just reviewing my ITR 2 for AY 15 - 16 and noticed that cost of acquisation column in capital gain schedule prepared by my CA in ITR was blank and only net sale consideration was updated by CA which was my Long term capital gain. In this case my cost of acquisation was 200000 sales consideration was 350000 and thus LTCG was 150000 but my CA kept cost of acquisation blank and update 150000 in sales consideration and same in LTCG. Can you please tell me if it is fine if cost of acquisation is kept blank and only LTCG amount is updated. Thanks Ibrahim
