Dynamic Subject in Workflow Task

Dynamic Subject in Workflow Task

I created a workflow task that will automatically create a task for me when I generate a new quote. The new task puts itself out 7 days and is just a reminder for me to contact the customer to see if they are ready to sign their contract (quote).

The issue I am running into is that when I generate the task, I want the subject to dynamically reflect either the Contact or Account name so that I know who to call at a brief glance in either the Zoho CRM home page or my Outlook Tasks.

I tried this as the subject of the task: Follow up with ${Contacts.First Name} ${Contacts.Last Name}
but it doesn't work... any ideas?
Thanks!
