I am using a validation data formula, initialy I have it set up to use
only the range (A1:A24) and (B1:B24) now I want to expand the range to
(B1:B30) (A1:A30)
Initial formula:

=IF(ROW(A1:A24)-ROW(A1)+1>COUNT(B1:B24),"",INDEX(A:A,SMALL(B1:B24,ROW(INDIRECT("1:"&ROWS(A1:A24))))))

When I go to the data validation window and modify the formula as
follows:

=IF(ROW(A1:A30)-ROW(A1)+1>COUNT(B1:B30),"",INDEX(A:A,SMALL(B1:B30,ROW(INDIRECT("1:"&ROWS(A1:A30))))))

There is not changes the range still reads the initial formula and the
new rows
read as A48 , A49....

I would like to know what should I do to modify my data as the second
formula.
