Hi list,
I'm using text variable and pagelist to display group of members that follow certain criteria. Ex.:
In the Member/Pierre page I have:
(:Director:John:)
I then use page list in John's page to show that he is the director of Pierre:
(:pagelist group=Members dir=John fmt=#memberperdirector:)
This displays a list of people supervised by John. I put the word "Supervise" before the pagelist and this is wonderful!
However if, inadvertently, John do not supervise anybody, I would like NOT to display the word "Supervise". In other word, I would
like to know, before results are displayed what is the count of the pagelist operation.
Is this possible?
Pierre
