Когда я добавлю surat_tugas_nominatifs.jml_hari в groupby, на нем будет отображаться имя двойного сотрудника

Как можно вычислить сумму penginapan+transport+harian? На самом деле уже есть общий расчет, и числа появляются, но они не могут фильтроваться как c и des c. Я пытался написать -

selectRaw('Count(surat_tugas_nominatifs.transport_lokal+ surat_tugas_nominatifs.cost_inap + surat_tugas_nominatifs.harian) AS Total') 

Это не выдает ошибку, но все еще не может фильтровать как c и des c.
