"Ви будете іти на стадіон?"

Translation: Will you go to the stadium?

[mizail]

May I say "Are you going to go to the stadium?"?

[Olly_1052]

More natural is "Ви ПІДЕТЕ на стадіон?"

[XrosFate]

Why isn't it стадіоні?

[Vinnfred]

на стадіоні means where? at the stadium
на стадіон shows direction: to the stadium

[SilverCharacter]

Walk is one of the suggested answers. Why won't it accept it?
