To correct this error go to the extended tab of the student's profile and change the value in the Funded Hours field under the School Information heading. The maximum value that can be entered in Funded Hours is 15.
Where a child has a 30 hour code and receives 30 hours of funding the extra 15 hours would be listed in the extended childcare hours field.
Once you have updated the value in the Funded Hours field, click Save at the base of the tab, then recalculate your Census.
