Column A Column B Column C Column D

TOA Apple
TOA Apple
TOA Banana
TOA Grapes

Any help is really appreciated, Thank you!!

Poor titles are less likely to get your post answered.

Since this is your first post I'll change the title for you on this occasion but please note for future posts.

In D1,

=INDEX($B$1:$B$8, MODE(IF(($A$1:$A$8 = C6) * ($B$1:$B$8<>""), MATCH($B$1:$B$8, $B$1:$B$8, 0))))

Paste the formula in the formula bar, press and hold the Ctrl and Shift keys, then press Enter.

It does work; the formula MUST be confirmeed with Ctrl+Shift+Enter, not just Enter.

Try again, and post a workbook rather than a picture if you still have problems.

As shg says, you haven't confirmed with CTRL+SHIFT+ENTER

I think the formula needs a tweak anyway, I put this version in D1

=IF(C1="","",INDEX($B$1:$B$8, MODE(IF(($A$1:$A$8 =C1) * ($B$1:$B$8<>""), MATCH($B$1:$B$8, $B$1:$B$8, 0)))))

then I selected D1, pressed F2 to select formula then held down CTRL+SHIFT keys while pressing enter. Curly braces like { and } appeared around the formula

I copied formula down and got results attached
