I have a index match that needs additional criteria. The formula
references a separate sheet called "INPUTS" and is referencing a number
associated with a price that looks like this:

cost size
..80 124
..90 148
1.00 156
(and so on)

here is the formula
INDEX(Inputs!$A$456:$A$461,MATCH(B6,Inputs!$B$456: $B$461,0))*B36) -
the multiple at the end is a total quantity. the b6 is the size

Here is what I am stuck with. I want to add another criteria for the
quantity. So something that would add in match (quantity less than
30000,quantity greater than 30,000 but less than 40,000, greater than
40,000 but less than 50,000)

at the end of the day I am looking for something to do this: If the
size is 124 AND the quantity is 30,000, then multiply the quantity by
..80)

maybe it should be VBA.

thanks for any help!!!
