I have a list of tickers and associated values that's an array resulting from sorting another column using the sort formula. I want to see if I can use a formula in excel to filter that array (C4 through D14) to show me the combination of tickers whose values sum up between 500M and 510M. Any ideas?

Excel Facts

What do {} around a formula in the formula bar mean?
{Formula} means the formula was entered using Ctrl+Shift+Enter signifying an old-style array formula.
Here is an attempt although I am not sure if it is the desired output:

Excel Formula:
=LET(
tags,C4:C14,
amounts,D4:D14,
min,D1,
max,E1,
combinations,TEXTAFTER(DROP(REDUCE("",TOCOL(amounts),LAMBDA(a,b,VSTACK(a,a&" | "&b))),1)," | ",1),
sum,DROP(REDUCE(0,TOCOL(amounts),LAMBDA(a,b,VSTACK(a,a+b))),1),
filter,FILTER(combinations,(sum>=min)*(sum<=max)),
array,--(IFERROR(DROP(REDUCE("",filter,LAMBDA(a,b,VSTACK(a,TEXTSPLIT(b," | ")))),1),0)),
total,BYROW(array,LAMBDA(a,SUM(a))),
column,TOCOL(HSTACK(array,total)),
tables,FILTER(column,column<>0),
tag,XLOOKUP(tables,amounts,tags,"Sum:"),
HSTACK(tag,tables))

I see what you are doing. Very interesting approach but not quite what I am looking for. I appreciate it though!!

Here's one way to do it but limited to 20 items since the row limit of Excel is 2^20.

Thanks for the feedback. Could you please specify what is the desired output?
