TDS Revised Return

I have filed TDS Ret by nsdl software for Q1. But now I need to revise the return. When I am trying to upload the fuv file, it asks to give both Original RRR ni and Previous RRR no.
Since I am correcting this return for the first time, I put the original 15 digit RRR no in both column. But after uploading, it says "rejected" showing the error msg-
Line No-2. Error Code- FV-BH-210091
Error Descripttion- Invalid Previous RRR No.

Pls help.
