Ah, yes, MPM7, you've been hit by the dreaded server burp! If I understand it, you don't write the PHI file; it is generated from the OBJ file (created in an external modeller, usually) and the Hierarchy Editor, or something like that. And if you use both this forum and Willow's PFO, and maybe the Poser Mailing List, you'll find all the help you need, and then some! :-)
