I have a python addin combox. Based on the selection of the combobox the user will get a message. When I test it inside Arcmap, I can see an error in the python window. Can anybody tell me what's wrong with my code that is producing this error? ThanksThis is the error:SystemError: NULL object passed to Py_BuildValue
