    How to identify an empty variable?

    Doron Reichenberg

      Hi,

       

      I have a variable named "MaxNumber". I want to create a chart expression like:

       

      IF $(MaxNumber) is empty then... else...

       

      What is the exact syntax? I tried to use '' or "" or ' ' but it doesn't idntify the empty variable. Also, ISNULL() doesn't recognize "empty" as "Null"...

       

      Thanks,
