TypeError: Error #1009: It is not possible to get a zero
pointer object.
I want to have a listener on a chart. When I click on it, a
number appears in a box.
I marked the coding which makes the TypeError with X below.
I just wonder, it works in a small programm, but in mine not?
Somebody can tell why?
Thanks a lot!
