Have you double-checked it’s the right ID in the editor 
Seems you’re using the Wix IDE, right? There’s the option in the bottom left to “Sync site” - it might be that the IDE hasn’t synced with the site in a couple of mins and the ID was changed within that time.
Tell us in more detail what you want to achieve using your code, so it will be easier for us to understand and give you an answer. 
Please do not use pics to show your code.
Instead use the integrated CODE-BLOCK-FUNCTION inside the POST-EDITOR.
Anybody has the time to retype all your code from a pic. Thanks.
