Filling in my form D46P for over 70s

i very recently sent in same form, but foolishly wrong, health questions are confusing, and got mine back, what i did, was where it says yes and no, i put a cross in box no, and proceeded to cross every condition, thinking i should because, i had none of those conditions, however when i studied the question properly, if you do not have any of said conditions, you leave boxes blank. not sure this will help, but hope some where along the line it has.
