Oh! I have a spreadsheet tracker that I hooked up to my code to automatically update pogress. I’m on mobile right now but if you check the forums the template/guide I used to set it up should be in the coding board as one of the most recent topics!
Sorry for the delay. Here's the skeleton of the code for the sidebars. You'll need to put this in your overall code. The CSS will determine how the sidebars will look (such as width, borders, etc.) so customize that! The HTML code below creates the table that uses the sidebar CSS information. The center area (id=container) is exactly how mine is currently set so maybe don't mess with that.
