Answer 1

Did you write this ode by yourself??

Line 6 of JS: "element" is not defined. It iterator is "buttons" according to line 4.

Line 19 of JS: There is no html element with that id?

JS can only access the html elements once the DOM is fully loaded. You can, for instance, wrap all your JS in
window.onload = () => {
...
}

Answer 2

your id is wrong in the html. you have an empty space between input and Box:

<input type="text" id="input Box" value="0"
placeholder="0" disabled>

also:
string = eval(string)
instead of
string = string(eval(string))

but also don't use eval as much as possible...
