There is a problem with the volume in one of your daily time records.
First you must find the daily time and then make the necessary changes.
Go to Reports » Farm » Manpower Complement.
The date range should be the same as your payroll period. Look for any earnings that show up as #Error instead of a proper amount.
Take note of the date, field number, employee and work.
Go back to the Field Input (Field » Field Input – either Labor or Extras) and go to the date and field you noted earlier. Now find the employee and his work. Delete that DTR and enter the daily time again.
Prepare the payroll and you will be able to view the Payroll Summary (with fields).
