keypad.addEventListener(keypadEvent);

I’m confused how to fix code and also why that code which is keypad.addEventListener(keypadEvent); is declared in this scope? someone let me know please

I think it's because you spelled "Event" wrong. Try "KeypadEvent", not "KeypadEvnet".

I'm confused how to fix code

Why do you think the improperly posted code needs fixing?

and also why that code which is keypad.addEventListener(keypadEvent); is declared in this scope?

What scope do you think it should be "declared" in? Code is not declared. Variables are.

If you foolishly insist on putting the { on the line with the function declaration or the if statement, atleastusesomespacesoitisrecognizable.
