So on a reservation page a user assigns guests to rooms. To calculate room rates per guest a count is needed of the number of guests residing in each room. The reservation page gathers all entry info and then calls another page to calculate rates. It's the calculate page that's the issue. This page has a recordset that provides a listing of all guests in a particular reservation and the total number of guests within each guests room. I then used the Data Assist update multiple record update server behavior to update all guests records with a count that is a column in the recordset. I followed the WA instructions to create a repeating region and then add the data assist update record (multiple) server behavior. Does that make sense?
