What is wrong with it?

Answer 1

Hello,
This is your code:

<div id="myDIV" style=" visibility : hidden;">hello there <br>
<button>hello</button onclick="hel()" type="submit">
<button onclick="noCommm()">...</button>
</div>

Clearly, you've placed attribute onclick="hel()" in closing button tag. Update onclick="noCommm()" to onclick="hel()" and the code will work.

Thank you a lot for your help! I was focusing on the functions and didn't see that I had misplaced it.
