Description : How can I represent an ordered tree structure in FileMaker Pro 10?
Last Answer : I’m not really familiar with ‘ordered tree structure’. Is it just a graph? If so the only graphs I have seen in FileMaker are done as webpages and viewed in the Web Viewer. Here is a good forum site for FileMaker and its free to join (others I have seen are pay sites).
