Standing an already standing target

By Ivengar, in 2. AGoT Rules Discussion

For cards like Frozen Outpost that say " Kneel Outpost to choose and Stand 1 defending character. Until the end of the challenge that character gets +2 SRT."

Would I be able to use it on a character that dosent kneel to defend to still get the +2?

Note, however, that the "stand" part of the effect is considered to be unsuccessful when you choose a character that is already standing. So if the effect said "THEN until the end of the challenge, that character gets +2 STR," you couldn't use the card on a character that was already standing because the success of the STR modifier depends on the success of the standing part of the effect (because of the word "then").

Great thanks Ktom!
