Sir, i have registered with the tcs portal. My reference id is DT[protected] and password is WiS!549UCo. Now i am filling the application form but there comes an error showing invalid form. It says that " Please check the 'To Date' of 'X details' as it does not match with the value provided for 'SSC year of passing' in previous section of the form". Can you please tell me how to resolve this error so that i can apply for the off campus drive.
