I want to create a giveaway but i can't find a title

I don't want to write this to the Support Group because i sent them a message about something else and there are 2 weeks of silence so i ask you, fellow gamers. I want to giveaway DLC to Binding of Isaac which is "Wrath of the Lamb". I can't find it on the list, even tho some people created such giveaways. Can you help? ;)

PS. I'm sorry for any mistakes, english is not my primary language.
