GSTR 3B

That's I'm following but its shows the error as I enter the amount of CGST as 

"You do not have sufficient cash balance in Central Tax to utilize or pay your total liabilities."

I have uploaded the image.

Actually the Tax Payble is around Rs 18000. So in which, i.e. CGST and SGST, I have to pay the tax

Tax Payble is 18578.32 approx

But it say that Central Tax balance is not sufficient

Ok no Problem , I understand that

One more thing, how will I adjust the amount of RCM as it shows 980 of Each CGST and SGST, I have to pay it or not.

I have entered the amount in both Table 3.1 and 4
