I have a session variable that's being populated by a parameter with the AllowEmptyDynamicValues option set, from that I'm using a show to display further parameters if the value is not empty or the value offair, but only the first value is processed in the show conditions.
<A>-A|Value|[pagevar:EventStatus]|!=;offair only works against a blank variable.
<A>-A|Value|[pagevar:EventStatus]|!=offair; only works against the variable being offair.
The '!=' strictly follows an equals comparison (case and culture insensitive). If you want to configure a contains expression, you should use the "regex=". In that regex you can do a negative lookup with the "?!" regex part.
Aha you’re trying to add multiple conditions in one go!
In that case you need to define the comparer in each of them. In your case here for instance: “|=onair;=scheduled”
As the values for the does not equals will be an empty string or offair I’ve changed it to the two values it should be to show instead.
-A|Value|[pagevar:EventStatus]|=onair;scheduled
