Trevor said <snippet> - Assign BMD flags as appropriate. - Set BMD icons associated with those flags to display on diagrams. <snippet> Expressions are far superior than Flags because once setup you never need to do anything else. You do not have to keep remembering to set Flags. See the FHUG Knowledge Base that has worked examples along those lines: http://www.fhug.org.uk/wiki/doku.php?id=how_to:using_flags_and_icons_and_expressions Happy New Year, Mike Tate
