List validation for when a new date is entered, require an attachment.

Copper Contributor

Hello -- We have a SharePoint list where we track user's completion of annual security training and the related certificate. What we want to do is that when a user enters a new annual security training completion date, then require them to upload an attachment (the certificate). 

 

I did some searching and know that it's possible for a Yes/No field to require an attachment, but I'm not sure how to write a formula that looks at a date field.
