Edit: I used a variable in the argument for getElementById in line 52 also and it worked. I want to do the same here. It doesn’t work because logging it to the console returns null.

Answer 1

Looks like you got it to work?

Answer 2

You are supposed to wrap it in quotation marks
………
document.getElementById("current PieceID");
………
Happy Coding 💗
