File Field Validation

File Field Validation

Hello all,

We are tracking our customer NDA agreements in our CRM and have created 2 fields to do so, an execution date field and a file upload field. 

I want to create a validation rule to ensure that when the execution date field is populated that the file has either already been saved or is going to be saved along with the execution date. 

I tried using a validation rule based on a Deluge script however, it seems the Deluge script doesn't get any info about the file upload field to act on. 

Does anyone have any ideas on how to achieve this?
