前スレ４の５０９が貼った直近３件の予定をシーンに表示するタスクだけど、初心者の私にはいくつか意味が分からないところがあって、タスクを入力する事ができないｗｗ

すごく初歩的な質問かもしれないけど、
１、A3からA5のToには何を入れればいいの？何も入れなかったらエラーになっちゃいます。
２、A7の下の〈loop_b〉、一体何を入力すればいいの？
３、A9の%cal_title(#)、この(♯)は何の意味があるの？このままtitleの後に入力していいの？
４、A13の%cal_title(%count_a)、この(%count_a)はtitleの後に入力していい？
いっぱい質問してごめんなさい、お願いします。。
以下、問題のタスク。
