Problem while filing ITR form 2

I had already filled it but the error was still there. And on that note I also wanted to ask how to enter negative figure in those ("F. Information about accrual/receipt of capital gain") since I have a slight loss in 1 quarter while gain in other 4 period range.

I also tried entering 0 in place of negative figure and carrying it and adding to next period to have the exact total which I have declared under gains.

Already filled the required schedules for me. And all these schedules are showing green tick besides them. And even the capital gains breakup is being displayed in Total income but not under taxation at special rates.

I already did that's why I had earlier replied that I carried them to the next period meaning I added them to the gains in immediate period range that followed.
