Hi,

I am using the following formula and it has been working great but all of a
sudden today it stopped working and now shows #ref error or sometimes it will
give me a date of Jan 3 no matter what the date really should be. What is
wrong?

=INDEX(BDData!E:E,SMALL(IF(BDData!D$1:D$16200=E$5& B$11,ROW$1:$16200)),ROW(1:1)))

The lookup value is in BDData!D4010 and the value I want is in BDData!E4010

I use the similiar formula pulling from a different worksheet with great
success:
=INDEX(Data!H:H,SMALL(IF(Data!E$1:E$16200=E$5&B$16 ,ROW($1:$16200)),ROW(1:1)))
