Question: How do I filter values existing in one range but not in an other?

### Formula in B13:

=INDEX(One, MIN(IF((COUNTIF(Two, One)=0)+COUNTIF(C12:\$C\$12, One)=1, ROW(One)-MIN(ROW(One))+1, "")), MATCH(0, COUNTIF(Two, INDEX(One, MIN(IF((COUNTIF(Two, One)=0)+COUNTIF(C12:\$C\$12, One)=1, ROW(One)-MIN(ROW(One))+1, "")), , 1))+COUNTIF(C12:\$C\$12, INDEX(One, MIN(IF((COUNTIF(Two, One)=0)+COUNTIF(C12:\$C\$12, One)=1, ROW(One)-MIN(ROW(One))+1, "")), , 1)), 0)) + CTRL + SHIFT + ENTER

### Formula in B21:

=INDEX(Two, MIN(IF((COUNTIF(One, Two)=0)+COUNTIF(B\$20:\$B20, Two)=1, ROW(Two)-MIN(ROW(Two))+1, "")), MATCH(0, COUNTIF(One, INDEX(Two, MIN(IF((COUNTIF(One, Two)=0)+COUNTIF(B\$20:\$B20, Two)=1, ROW(Two)-MIN(ROW(Two))+1, "")), , 1))+COUNTIF(B\$20:\$B20, INDEX(Two, MIN(IF((COUNTIF(One, Two)=0)+COUNTIF(B\$20:\$B20, Two)=1, ROW(Two)-MIN(ROW(Two))+1, "")), , 1)), 0)) + CTRL + SHIFT + ENTER

### Named ranges

One (B2:D4)
Two (B7:E10)
What is named ranges?

(Excel 2007 Workbook *.xlsx)

IF(logical_test, [value_if:true], [value_if_false])
Checks whether a condition is met, and returns one value if TRUE, and another value if FALSE

INDEX(array,row_num,[column_num])
Returns a value or reference of the cell at the intersection of a particular row and column, in a given range

SMALL(array,k)
Returns the k-th smallest row number in this data set.

ROWS(array)
Returns the number of rows in a reference or an array

MATCH(lookup_value,lookup_array, [match_type]
Returns the relative position of an item in an array that matches a specified value

INDEX(array,row_num,[column_num])
Returns a value or reference of the cell at the intersection of a particular row and column, in a given range

COUNTIF(range,criteria)
Counts the number of cells within a range that meet the given condition

MIN(number1,[number2])
Returns the smallest number in a set of values. Ignores logical values and text
