innerHTML changing my formatting?

I had the lists of questions outputting nicely, but when I changed the print function to use innerHTML per the video, it came out as unordered lists with the questions on the next line down from the bullets. Why would this happen?

function answerList(list) {
  print("<ol>");
  for ( i=0; i<list.length; i++ ) {
    print("<li>");
    print(list[i]);
    print("</li>");
  }
  print("</ol>");
}

The "print" function shown in the video is intended to be used only once, and it would replace any previously output content if used again. So I expect yours is a bit different or you wouldn't see any output at all.

Please show the complete code to make it possible to analyze your issue. If you have it in a workspace, just use the "snapshot" (the camera icon) and post the link it gives you.

Your "print" function is a bit different from the video in that it adds to the element contents instead of replacing them. That in itself wouldn't cause any problem, but it looks like the browser is trying to help by adding closing tags for you when you update it with only open tags. This leaves the text outside of the list items.

You can avoid this issue if you use the method shown in the video where the message is assembled into a variable ("html") first, and then "print" is called only once.
