嘿，當我按下按鈕時出現問題我在控制台日志中有一個錯誤，說我的 function 未定義

Question

因此，當您單擊按鈕時，控制台會顯示：“project3.html:48 Uncaught ReferenceError: findnembers is not defined at HTMLButtonElement.onclick (project3.ZFC35FDC70D5FC69D2539883A822C)” 太感謝了

    <script>
        function sumdigits(num) {
            sum = 0;
            while (num) {
                sum += num % 10;
                num = Math.floor(num / 10);
            }
            return sum;
        }
        function findnembers() {
            var counter = 0;
            var list='<ol>';
            for (let i = 0; i < 9999; i++) {
                var ezer = sumdigits(i);
                if (ezer === 9) {
                list+= "<li>" + i + "</li>";
                 counter++;
                }
            list += "</ol>";
            }
            var print=list+
            <p style='text-align: center;font-size: 1em; font-weight: bolder;'>"The  sum of digits of those number is 9, and they are in the range 0 to 9999 inclusive and their quantity is "{counter}</p>;
            document.getElementById("rslt").innerHTML=print;
        } 
</script>
</body>

正如@kinglish所說的那樣。 應該是這樣的

 var print=`${list}<p style='text-align: center;font-size: 1em; font-weight: bolder;'>"The  sum of digits of those number is 9, and they are in the range 0 to 9999 inclusive and their quantity is "${counter}</p>`;
