javascript - onchange で複数の関数を呼び出す

Question

これはすべて私の経験を少し超えていますが、私はできる限りあらゆる場所を調べ、今日これまでに 6 時間このことを調査しましたが、レンガの壁にぶつかっています.

ユーザーが2つの変数を入力すると、それらの2つの変数から12の異なる数字が吐き出されるテーブルがあります。これらの数値がプレーンテキスト文字列として読み取り専用テキストフィールドに吐き出される問題があり、(米国の) 通貨として表示する必要があります。表の入力フィールドはすべて onchange を使用して計算を行う最初の関数を実行していますが、オンラインで見つけた 2 番目と 3 番目の関数は実行できません。
