E-tds returns filing

Could anybody please help me.

I m facing problem in filling of e-tds return.

I uploaded the return after validating the file to tin.nsdl.com but it got rejected by NSDL with the error code (T-DB-2017) and error descriptttion is (Regular statement with same periodicity ( combination of Form, TAN, FY and Quarter) cannot be uploaded more than once).

I am not understanding what exactly the error is.

Still i m waiting to file the Return so please guide me how could i complete it.

Thanks.
