 Taking the correct decision among the two remaining alternatives in A7 makes it quite an enjoyable puzzle (won't spoil which of the two numbers is the correct one)

 A little tip – this is quite a tricky puzzle for me:
A7 is the smallest cubic number

 Very nice. Field 7 does not have so many alternatives; one of these works well.
