using a business rule to require "work notes" field be entered

[patricklatella]

hi community!

I'm developing a custom form that has a State field.   I also have the OOB "Work Notes" field on the form.   I need to require the "Work Notes" field be filled with something to enable changing the state of the record FROM any of 3 "closed" states.   I'm working with a business rule to achieve this.   However a condition that is not possible is "work notes is empty".  

I'm working on an advanced condition script, but am struggling.   any thoughts?   thanks!
