What's wrong with this?

Hello. Can somebody tell me, what's wrong with my code? I am trying to use what I learned in JavaScript and HTML courses. I want to change value of progress bar, but I cant select it. https://code.sololearn.com/WCNV4drAAYK1/?ref=app

The script is being run before the window is loaded, therefore the script can not find the progress bar element. try: window.onload = function() { bar = document.getElementById("bar"); bar.value="73"; } or put your JavaScript into a function and call it from a tag e.g <body onload = "functionName()">
