>Hello,
>if you double-click a band header in report designer, a pop-up window appears, in which you can define an 'on entry' and an 'on exit' run expression. How are they supposed to work? I have never been able to make them work. Can I initialize report variables there? Or make some counter count? Could please somebody post an example?

You can call your own UDF, call a method of any object in scope at the time, or execute a simple one liner like x = x + 1.
