Hello I have a scheduled workflow creating records in Membership Fee entity for every Member record (related by M- to -1 respectively). However the 'name' field (labeled as 'Fee') of the records are not being created in Membership Fee (image below):

I am trying to use a formula in the scheduled workflow to create the Fee name of the form: Member's First Name Member's Last Name.
Workflow + Formula:

What am I doing wrong? I tried concatenating contact.firstName and contact.lastName, assignedUser.firstName and assignedUser.lastName, contactName, contact.name... with no result.
