You see here how important it is to always provide full problem
description. Usually, beside "Error Type" and "Error Value" the
traceback, too, is very important.

The error information above tells you that your problem is
not the "?num" but your "External Method".

Unfortunately, the information is not very precise.
You need the following background information:

   When an "External Method" cannot be loaded (e.g. because
   its source is not found), then it is represented as "None".

You get more information, when you visit the "External Method"
in the ZMI and press "edit".
