I believe you need AND rather than OR:
T060ProductsGlass::Category ≠ "One"
T060ProductsGlass::Category ≠ "Two"
so show works if Category is NOT "One" & NOT "Two"
Thank you Beverly Will try that
If you are placing this so that "Hide object when" is used, then "OR" with the positive:
Hide ... when
T060ProductsGlass::Category = "One"
T060ProductsGlass::Category = "Two"
Thanks for the help works will
You are a legend
can you mark an answer as correct (even your own comments), so others know the question is answered?
then perhaps you should mark Beverly's answer as correct and not your own.
