Answer 1

When your code reaches line 51 $("#dropDown") element has not loaded. It's outside of $(function(){})
Move it to the onload callback.

Try to use a better code editor

Answer 2

Kevin ★ I use Acode editor for android to code it, then pasted it here in sololearn and it stopped working. Although, I've been able to fix the error with some help, thank you.
