Answer for VALIDATION ERROR
Please check pan card details properly:-
Status of your – check 4 letter of your pan if it is C- you must select company
P- for individual
F- for firm
Also check Name as per pan- It must be written in same manner i.e with spaces and dots if any
example PV RAMSWAMY IS written on PAN than you should write in the same way.
Dont write like P V RAMASWAMY OR P.V RAMASWAMY or any other combination.
Also check date of birth and state you selected.
Hope this will help else you may write again here.
