Apparently I'm an idiot... :(
This has me stumped. I've tried SUMPRODUCT, various array formula (Ctrl+Shift+Enter), non-array formula, VLOOKUP, XLOOKUP, INDEX/MATCH)
At this point I've developed a Glazed-Over mental block. So now I'm reaching out to the sane Excel users.
I think the uploaded image thoroughly explains what I'm trying to achieve.

Thanks for any help offered. I know everyone's time is valuable and so I appreciate any charity on this matter.
Jase.

Excel Facts

Formula for Yesterday
Name Manager, New Name. Yesterday =TODAY()-1. OK. Then, use =YESTERDAY in any cell. Tomorrow could be =TODAY()+1.
MrExcel has a tool called “XL2BB” that lets you post samples of your data that will allow us to copy/paste it to our Excel spreadsheets, so we can work with the same copy of data that you are. Instructions on using this tool can be found here: XL2BB Add-in

Note that there is also a “Test Here” forum on this board. This is a place where you can test using this tool (or any other posting techniques that you want to test) before trying to use those tools in your actual posts.

Also what version of Excel are you using?
Please update your account details to show this, as it affects which functions you can use.

Assuming you're using a table, and that the dates are in increasing order by row, as in the example:

UPDATE: as per Fluff's recommendation, I installed XL2BB. However I was unable to edit my original post because "time had expired" so I'm replying with the Excel info.

10When a row on the INDEX column has evaluated TRUE
11Then take $A$1 and look through that Row, considering Columns VALUE1:VALUE5
12and return the Exact-Match-or-Next-Smaller value.

14In this example, the returned value would be 1/24/2021

Thanks, Eric. But this won't work in my situation.
I should have been more clear. I need the result returned in, say, B1.
I can't just add another column to the table.
I need the formula to look through the table, find what has evaluated to TRUE in the INDEX (MY_INDEX) column, and return the result.

Try this in B1:

Excel Formula:
=LOOKUP(A1,INDEX(Table2[[VALUE1]:[VALUE5]],MATCH(TRUE,Table2[INDEX],0),0))

Try this in B1:

Excel Formula:
=LOOKUP(A1,INDEX(Table2[[VALUE1]:[VALUE5]],MATCH(TRUE,Table2[INDEX],0),0))
Eric,
I marked as solution. Many thanks! Your solution gets me back on the road and out of the ditch!!!
