Or you might need to use a comparison calculation to determine how many of your customers have ordered products during the past three months. When examining the power of scripts and calculations within FileMaker, you start to realize that FileMaker is not just for storing data. The real power of FileMaker is in its ability to manage, manipulate, and provide information about the data — which requires performing calculations on the data.
