I have a list of numbers to add if they meet two criteria and I have been
trying to use the conditional sum feature in excel.

Column A is a list from 1 to 5 and I want to sum all the numbers in column B
if Column A is either a 1 or a 5.

Below is the array formula the conditional sum feature produces and it
returns 0 when it should return 11. The array works if there is only one
variable but not multiple.

Can someone tell me why its not working?

Thank you.

{=SUM(IF($A$3:$A$10=5,IF($A$3:$A$10=1,$A$3:$A$10,0 ),0))}
