When you click on the button the Console says:
project3.html:48 Uncaught ReferenceError: findnembers is not defined at HTMLButtonElement.onclick (project3.html:48)
Why is that?

var print=list+

as @kinglish said quoting . it should be like this
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>`;
