I've been perusing the forums for how to have a checkbox column check a duplicate of a row and I can't get any of them to work the way I want them to. 
Criteria for checkbox being checked: 
- Row ID shows up more than once AND
- Created column is not the most recent
Once I get this figured out, I will have an automation where the rows with checkboxes checked are moved to an archive sheet. Therefore, I want the most recent version of a Row ID to stay unchecked, therefore staying on this sheet. In the screenshot below, I've shown which box would be checked. 
    
        
             
    
Thank you for your help!
