I need help finding the root of the problem. When I fix one error another one pops up like a chain reaction. What's the cause???

Your javascript will run before the document is loaded, so all the `.getElementById` calls return null. You need to wrap your entire code in one of these: window.addEventListener("DOMContentLoaded", () => { // code goes here ... });

Thanks Schindlabua, Abhay. Curious thing is that the code works perfectly on another editor but SL had an issue with it, anyway I'm glad its a simple fix
