if you are trying to use a variable in more than one function nesting, callback nothing works, what i did your variable declare it outside function first, just write functions as per normal, and then write say second function separately, now the i don't know what your function is, when it comes to displaying it, i found server could'nt find variable so my last code that declares x(because that hold latest value of x) say x = document etc, put that before final display code(be careful where you put it, I put at top of second function), for me that was the thing that made it work, hope it helps(took me 2months work)

Beginner here. Doing a course but it's so slow. I do better dissecting complexities like this and connecting the dots my own. In short - thank you!
