Malcolm, this does not give me what I want. Let me give you an example:
Data Field called Treatment can contain one or many of the following: Vaccine, Fecal, Bath, Treatment, etc. I only want to see those records that DO NOT CONTAIN "Vaccine" and in addition, I don't want to see the records that contain Fecal, Bath, Treatment, etc. In other words, I only want the records that are Blank for the word vaccine and while this data field may have other values in treatment, I don't want to see those records nor do I want them counted. It is a null for vaccine, but don't show me anything else.
