Error during filing itr

You should post a grievance

On which step you get a error, I mean after entering amount in respective heads or some where else

It's clear that you have not taken all the dividends but only those that are in 26AS. Take the actual dividends as per bank statement and the Form 16A of all companies that deducted TDS.

1) take actual figure of divident from 26AS
2) Also add, divident recived, but not reflected in 26AS
3) show, for which quarter, the dividend are recived, for advance tax purpose
4) Enter correct details from salary, including 26AS, deduction
5) file correct itr....as applicable, in your case
6) conform, salary details are correctly entered

this, should resolve the issue
( I suppose, u r filing itr1)
it is quite possible, u must be making some mistake in salary statement....recheck it

Thanks for your advice sir i will follow your suggestions 

i am getting error while submitting itr after adding all details.
