Js error on click event.
Trying to make a passenger counter app and stuck on getting my save button functionality to work.
I get this error "'saveNumber' is declared but its value is never read.ts(6133)" when I try to set a saveNum var on line 27. I'm not understanding what I'm doing wrong here?

I dont get any error
Try refreshing the page
In this function
saveEl.addEventListener('click', function() {
let saveNumber = count + " - ";
});
It works if I remove let and just set
saveNumber = count + " - ";
But i'm confused as to why that is? can I not set let b/c I'm already setting count = 0 at the top?
