I have the following formula in Col C

=SUMIFS(C$275:C$379,$A275:$A$379,{"Idle Time","Oil stock *"})

The criteria "Idle Time" & "Oil stock losses" are in Col A.

I would like to add the values in Col C based on "Idle Time" & "Oil stock losses" which are in Col A

The formula =SUMIFS(C$275:C$379,$A275:$A$379,{"Idle Time","Oil stock *"}) adds the idle time value correctly, but ignore the values of Oil Stock losses

It would be appreciated if someone could assist me
