Hey Student,

Oh dear, this is a tricky one. It's definitely messed me up in the past. What's happening here is an issue of scoping and closures. A few things to point you in the right direction:

  1. Study block scoping versus function scoping in JavaScript
  2. Study JavaScript's variable declarators, var, let, and const, and understand the differences between their uses
  3. Study up a bit on closures in JavaScript
  4. With your new knowledge, try to make btnNum block scoped instead of function scoped
You can’t perform that action at this time.
