Co-Signer in form IM1344

[Keijeyn]

Hi it says in the complete guide that I should not leave any section blank in any form and need to write N/A.
In this case, i am confused if I should write N/A In all sections of the Co-Signer details, or I will just leave it blank? We dont have any co-signer.
Hoping for your response! Thank you
