Finding the last match in a list

[rowett]

I want to be able to find the last match in a list. To find the first match I use the MATCH worksheet function. For example MATCH("Chris", A1:A5, 0) finds the index of the first cell in the range A1:A5 containing the text "Chris".

How do I find the LAST cell in the range that contains "Chris"?

Many thanks,
Chris

I've been trying this for over an hour with MAX(IF()), which worked on one worksheet but not another, INDEX(MATCH()), LOOKUP()....you name it. Nothing worked but INDEX(SUMPRODUCT()) is perfect!

Perfect for what? Could you post a sample along with the desired result?

I was trying to create a summary page for car maintenance log. Here is the result:

=INDEX(maint_data[#All],SUMPRODUCT(MAX((maint_data[Maintenance Type]=A17)*(ROW(maint_data[Maintenance Type])))),3)

The summary page has a list of maintenance types (oil change, tire rotation, brake inspection, etc.). On the maintenance page, I keep a running log of all maintenance actions. The summary page then displays when the last action of the type was, and calculates when the next one is due based on my manual's recommended cycle.

Could you post 10 rows from this table (with headers included) along with the desired result for that bit of 10 rows?

Why 18,890 for Air Filter as there is no separate entry for this maintenance type?

That's a mistake, haha

 

[Aladin Akyurek]

That's a mistake, haha

But what should be the value?

That's the engine air filter.
