I'm having the hardest trouble figuring this part out. Even after doing some searching and people asking for the same thing. When i try to use it on my sheet it doesn't work.
I want to do excel's version of index,match,match. I've tried index(collect), join(collect), max(collect), but i am doing something wrong apparently.
I have a bunch of sheets where i'm trying to see the last location of an item. Each sheet can enter the same item. In a item finder sheet i have a column that you can enter the item and based on the formulas it will tell me if the item exists in those sheets by doing references. I need to retrieve the created(date) column using formulas, i have 2 criteria.
The formula i'm trying to do is
=JOIN(COLLECT({Created(date)}, {Item List}, Item@row, {Created(date)}, MAX({Created(date)})))
or probably best described like so
=Max(Index([Created(date):Created(date)],match(Item@row,{Item List},0),0))
the join(collect) worked good at first, but when i enter more information the formula results from the others go away and the newest entry pops up.
With my 2 criteria i want my end results to show the last time they were entered in any sheet and for the value to always stay on screen.
