If you cant trade huble bundle purchases, where are all the games from it coming from?

There's a button with a gift, right to the link of the game you want to give

I meant to give here, on this site, I already gave the batman games to a steam friend.

When your giveaway closes, there will be a link showing the winner's email on your created giveaway list.
You can also try contacting the winner on Steam by adding him/her as friend, then send the Steam gift/key/Humble Bundle URL though the chat window.

I apologize for this thread, I had never made a giveaway and just assumed it needed to be a steamgift in your steam invintory, all cleared up now. Honestly my own fault, sorry but thank you to those kind enough to help :D
