My goal is to assemble a text box creating a file name based on the fields which may or may not have any qualities. For example, a file named "Big Book" may be in French (FR) and/or in Large Print (LP) or PaperBack (PB). But it may have none of these conditions. So file names may be ...
Big Book
Big Book {FR}
Big Book {FR,LP,PB}
(there will be more information after this section, such as Year, Size)
So the logical thread would be ... FileName + "{" if there are any qualities + "," if there are multiple qualities + "}" to close out the qualities + Year ,etc
