First of all, Rik: It is not good behavior to post the same question three times, with a delay of 6 hours. This can not be excused by accidentally hitting the “submit” button twice.
Second: If you do not provide more information, you can not expect to get an answer. I looked into you recent posts and all have been of the same quality.
Third: logon to the production library and run the program (sorry, the answer is quite short but fits to your question. How should we know, what your QA and production environment look like?).
