SYMPTOMS
When you edit a content expression by using Microsoft Commerce Server 2002 BizDesk, you may receive the following error message:

An Error Occurred!

Cannot load expression. Expression XML is invalid. The operator 'not-equal' is not recognized, or is invalid for the argument types(s). The types/operators file may have an error: 'TypesOpsA.xml'.



CAUSE
This problem occurs because no validation occurs on an edit. When you change the operator to is not equal to, and then you do not specify either True or False for the third argument, you create an argument that is not valid. However, you can still save the argument.



RESOLUTION
To avoid this problem, create a new content expression.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
