Excluding specific cells from array formula

I am using this array formula to get the total number of minutes:
{=SUM(IF(ISERROR(Y2:BI2),"",Y2:BI2))}

I need to revise the above formula to exclude the following 3 cells: AV2, AY2, BB2

Thanks,
Andrea

HI,

pls try

{=SUM(IF(ISERROR(Y2:AU2);"";Y2:AU2))+SUM(IF(ISERROR(AW2:AX2);"";AX2:AX2))+SUM(IF(ISERROR(AZ2:BB2);"";AZ2:BB2))}

Try

=SUM(IF(ISERROR(Y2:BI2)+NOT(ISERROR(FIND((ADDRESS(ROW(Y2:BI2),COLUMN(Y2:BI2))),"$AV$2,$AY$2,$BB$2"))),"",Y2:BI2))

With commas instead of semicolons

{=SUM(IF(ISERROR(Y2:AU2),"",Y2:AU2))+SUM(IF(ISERROR(AW2:AX2),"",AX2:AX2))+SUM(IF(ISERROR(AZ2:BB2),"",AZ2:BB2))}
