Locating most current date in Found Set

[Shipbuilder]

Anyone know how to create a calculation that could be inserted after a found set is sorted and find the most current date in the found set? I have a list of employees with their daily job charge entries listed. The report that is produced sorts the jobs and seperate disciplines and also summaries the total hours for each discipline, however, now I need to have the report show the last day an

employee charged to this specific job and list that on the report in a field "Last Charge As Of".

Try a summary field defined as Maximum of Datefield.
