If you are not listing to eBay US, AU, CA, UK, eBay Motors US or Bonanza, you will need to get the HTML code for your listing description. To do this, click on the Code button. A pop-in window will open, and you will be able to copy your HTML code.
Note: You will not see the Code button if you have a token for the selected listing site. To turn on the option to see the Code button, go to Site Preferences and uncheck the option Remove 'Code' button if token exists.
