Oh, I’m retarded – I thought you said “horizontal lines” :S But I see what one it is :) 血（ち） is the kanji for “blood”, though I’m not sure why 団交 is highlighted and it’s getting you to draw 血…. It looks like you’ve had to draw those four kanji in the middle line in order (though I may be mistaken), but you’ve left the dictionary page (or whatever it is) for 団 open. I don’t know, but they are two separate kanji with no related meaning.
