Hi Katalin. I tried that but it only then showed the basic symbol - no detail which I needed. I have since explored the MVO set up, and that seems to have solved it. I can only ascertain that when upgrading from 17 to 18 the MVO settings were changed. I am now able to use MVO as the criteria on the object. Hope this makes sense. Thanks for your input. Mike
