Hello,

I have a draw chart sub which generates a runtime error "method
seriescollection object_chart failed" from time to time. It doesn't
happen all the time, probaly around 15% of the time. Below is the full
code. I'm running out of ideas now in terms of how to fix the problem.
Please help!!

Thanks a lot
