Need help creating formula field in tasks using Zoho CRM Pro.

I'm using Zoho CRM Pro and am trying to build a formula field (Let's Call it Field "B") in Tasks that will copy value from an existing task field (Let's call it Field A) to the new field I am creating (Field "B") if certain a certain value is in task field "C". Is this possible?
