This is a video walkthrough of how to modify a gift configuration with GC Volunteer Management. 

Before you start to modify, make sure the data files and configurations are set to look at the data points you need. For example, if you are looking to include anonymous gifts in defining if someone is noted as "has given", you need to be sending a datapoint on whether a gift is anonymous or not. 

Also make sure that if you are adding parameters to a configuration that you have the right set up to look for ALL of those criteria or ANY of those criteria, depending on your need.
