# how to find if any unique values in two columns for each value in one column

#### rishijain11

I have two columns. column A has text, column B has a numeric ID.

A B
Pizza 40
Candy 20
Soda 30
Broccoli 20
Pizza 40

Every time "40" appears in column B, I want to make sure that all the respective values for 40 in column A, are the same. In this case, they're all "Pizza".

I want to know if there are ever any multiple unique values. In this case, "20" has two unique values - "Candy" and "Broccoli".

How can I do this without having a formula that I would need to drag down all throughout a new column.

Ideally, I'd like to be able to have just 4 cells for 4 formulas (one for each unique numeric code). is this possible?

hope this was clear

perfect. thanks Eric.

In the case of column D, value "10". Since this doesn't exist in column B, is there a way I can have it return text other than "true"

Try:

=IF(COUNTIF(\$B\$2:\$B\$6,D2)=0,"None found",COUNTIF(\$B\$2:\$B\$6,D2)=COUNTIFS(\$B\$2:\$B\$6,D2,\$A\$2:\$A\$6,INDEX(\$A\$2:\$A\$6,MATCH(D2,\$B\$2:\$B\$6,0))))
