# appendChild error for nonexistent “Attach to” element

 * I’ve set the “Attach to” floater setting to `#main`, which exists on every page,
   except the checkout page. Since the element doesn’t exist, the browser console
   shows the error `Uncaught TypeError: Cannot read property 'appendChild' of null`.
 * [If it makes a difference, this is on WP 5.6 (jQuery 3.5.1) with jQuery Migrate
   disabled, but when WP 5.7 comes along, this will be the setup.]
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fappendchild-error-for-nonexistent-attach-to-element%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Thanks for reporting. That’ll be fixed in the next release. In the meantime, 
   a workaround is to add an additional selector that _is_ available on the checkout
   page, for example:
 * `#main, #checkout`
