Referencing Drop-down list error #n/a

[applefritter]

Hello,
I have a multi-sheet workbook and I am having problems with a cell in sheet 1 that references another cell in sheet 2. That second cell is populated by means of a drop-down list and I’m sure that’s where my problem lies but I don’t know how to fix it. I keep getting the #N/A error.
Here’s the breakdown of the sheets and cells involved.

Sheet 1 named “Days”
Sheet 2, named “PrimaryHistory”
Sheet 3, named “Lists” (This sheet contains all the various drop down lists used throughout my workbook)

This is my problem formula in Sheet “Days”, cell F12:
=INDEX(PrimaryHistory!$B:$B,MATCH(9.99999999999999E+307,PrimaryHistory!$B:$B))

• Where F12 should be the last populated cell from "PrimaryHistory" column B
• Where “PrimaryHistory” column B is populated by means of a drop down list of names from a list on sheet “Lists”.

I’ve tried creating the list off to the side within the “PrimaryHistory” sheet but I still have the same error. So what do I need to add to my formula to get it to give me the proper text?

How about
=INDEX(Pcode!$B:$B,MATCH("ZZZZZZ",Pcode!$B:$B))

If PrimaryHistory!B:B has only text-filled cells, your formula will return #N/A b/c its looking for the last cell with a number in it. Fluff's formula will provide the value in the last cell filled with text.

Here's an alternative that will find the value in the last filled cell regardless of whether it contains text or a number.

=LOOKUP(2,1/(PrimaryHistory!$B:$B<>0),PrimaryHistory!$B:$B)

Once I changed "Pcode!" to "PrimaryHistory!", that did it! Thanks!!!

Joe,
Thanks for the explanation! I was wondering but was too embarrassed to ask for the why's and how's.
