Pop-Up Note showing dynamic field value?

We want to create a pop-up note for a customer on the SO screen if ever today is > { a custom date/time field value tracking a tax expiration date}.

Is this possible?

If not, it would even be beneficial to add the field value to the Pop-Up note itself.

Could we have the pop-up note display the value of the custom date/time field, for example? That would be acceptable. 

Is this a matter of determining the correct bQL when creating the pop-up note? 

Here are the properties:

Here’s a version of the note showing where I’d like to see the field value. 

Open to ideas!
Thank you.
