dynamic excel array based on input - arrays

Question

I am looking for a little help in making a formula based dynamic array in excel.
KPI | Tgt | number | Weight
FCR | 0% | 1 | 45%
FCR | 60% | 2 | 45%
FCR | 80% | 3 | 45%
Leads | 45% | 4 | 25%
Leads | 50% | 5 | 25%
Leads | 200% | 6 | 25%
Attrition | 8% | 7 | 10%
Attrition | 12% | 8 | 10%
Attrition | 100% | 9 | 10%
Abandon | 1% | 10 | 20%
Abandon | 5% | 11 | 20%
Abandon | 200% | 12 | 20%
So if i have a Leads score in cell E2 as 3%, then i want output in F2 as Number 4 which is <45% hence 4.
PS: I have a spreadsheet but don't know how to attach it.

Answer 1

Try this in F2:
=INDEX(C:C,AGGREGATE(15,6,ROW(B:B)/((B:B>=E2)*(A:A="Leads")),1))
This will only return matches for rows with "Leads" in column A. This can be made into another reference if you have or want to put that into another cell instead.
EDIT:
Based on you're comment below, this formula works as well if entered as an array (CTRL + SHIFT + ENTER):
=INDEX(C:C,MATCH(1,(A:A="Leads")*(B:B>=E2),0))
EDIT 2:
We can cover our bases for an unsorted list in column B by combining the two solution:
{=INDEX(C:C,MATCH(1,(A:A="Leads")*(B:B=AGGREGATE(15,6,B:B/((B:B>=E2)*(A:A="Leads")),1)),0))}
