This video shows the problem caused when a value or values are NULL in your data. It also demonstrates a solution using the NZ function when performing arithmetic operations on data that includes NULLs. The term "Null" means the absence of a value.
This video has been resurrected from an older Access tutorial series by DataPigTechnologies. Even though Access looks different now, the concepts and functionality persist. Thanks to owner, Mike Alexander, for making these videos available for presentation once again. Thanks also to Jack Drawbridge and John Clark for helping get these valuable lessons back online.
