So I am working on a Visualforce Email Template and I am stuck. I am trying to pull a field from a related object to the one that the template would be generated from. When I put in the Child Relationship Name into the code it says that it is not a valid field. I know this is the proper name and I know I have done this before. Not sure what I am missing here.
