What does "Number of people served by your ministry" mean?

In the field we are asking approximately how many people you and/or your team serves in your ministry. For example, if you expect to WorshipPlanning.com (WP) to plan your contemporary worship service, this number would be the approximate number of attendees that come to the service. If you plan on using WP for every weekly service at your church, this number would be the approximate number of attendees you have all week.
