rbv_api.setFieldValue() with variables?

I am trying to use rbv_setFieldValue() to set a field based on a merge template. Is this possible? Below is my script inside of an Object Script trigger var x = "{!R801480.scholarship_name}" rbv_api.setFieldValue("scholar_application", {!id}, "application_document", x) I also tried this: rbv_api.setFieldValue("scholar_application", {!id}, "application_document", "{!R801480.scholarship_name}") The field I am trying to update, application_document, is a document template field. The name of the document template that I want to assign as the value for this field is the same as the contents of the "{!R801480.scholarship_name}" field.
