You may add staff members to the Expenditure Statement by clicking 'add new'.  

The name of the staff member can be typed directly into the 'Name' field, or you can click 'Select' which will allow you to search using the first few letters of a surname and/or initials.  

Click on the person you require from the returned list and then continue to complete as many of the data fields for that staff member as you can. Some fields may not be editable depending on which staff type you select.

For BBSRC:

Casual staff details should be entered under exceptional items and such claims will not attract the indirect cost addition.
