## Summary

To highlight the 3 smallest values that meet specific criteria, you can use an array formula based on the AND and SMALL functions. In the example shown, the formula used for conditional formatting is:

``````=AND(\$B5=\$E\$5,\$C5<=SMALL(IF(color=\$E\$5,amount),3))
``````

Where "color" is the named range B5:B12 and "amount" is the named range C5:C12.

## Generic formula

``=AND(A1=criteria,B1<=SMALL(IF(criteria,values),3))``

## Explanation

Inside the AND function there are two logical criteria. The first is straightforward, and ensures that only cells that match the color in E5 are highlighted:

``````\$B3=\$E\$5
``````

The second test is more complex:

``````\$C3<=SMALL(IF(color=\$E\$5,amount),3)
``````

Here, we filter amounts to make sure that only values associated with the color in E5 (blue) are retained. The filtering is done with the IF function like this:

``````IF(color=\$E\$5,amount)
``````

The resulting array looks like this:

``````{FALSE;100;FALSE;200;FALSE;300;FALSE;400;FALSE;500}
``````

Notice the value from the amount column only survives if the color is "blue". Other amounts are now FALSE.

Next, this array goes into the SMALL function with a k value of 3, and SMALL returns the "3rd smallest" value, 300. The logic for the second logical test reduces to:

``````\$C3<=300
``````

When both logical conditions are return TRUE, the conditional formatting is triggered and cells are highlighted.

Note: this is an array formula, but does not require control + shift + enter. Author ### Dave Bruns
