Hi Eric:

COUNTIF() will work for you.

Let's say we have a set of values in column A, say A1 thru A100. In B1 we
insert the value we would like to check. In B2 enter:

=(COUNTIF(A1:A100,B1)0) which will return TRUE if B1 is in the list

Does anyone know which function to perform checking any value within a list?
such as
a list {1,2,3,4,5,6,7,8,9}
a value {4}
then return true
Thank you
