Formula help - IF, OR, AND, VLookup? multiple conditions

[EMY245]

Hi all,
I have the following fields of data:

A2 'values': (shows the value 'low', 'mid' or 'high)
B2 ' ratings': (shows a value rating of between 1-5)

I need a formula to populate the %'s in the table below, based on the rating and value. I.e. If Rating is 1 and value is 'low' show 0, if rating is 2 and value is 'low' show 0.5 - is there a quick way to do this without typing out each individual scenario for an incredibly long formula?

[TABLE="width: 500"]

There may be, but it really isn't at all clear what the logic is for the values beyond what you have already told us.

Hi, maybe you adapt something like this:

Excel 2013
	A	B	C	D	E	F	G	H
1	Value	Rating	%		Rating	Low	Mid	High
2	Mid	3	0.5		1	0	0	0
3	High	4	1		2	0.5	0.5	0
4	Low	5	2.5		3	1	0.5	0
5	Low	1	0		4	2	2	1
6					5	2.5	3	3.5

Her it is. Place this moderate-length formula in cell B2 and copy across and down:

=ROUND(SUMPRODUCT(CHOOSE($A2,{1,1,1,1,1},{16,8,4,2,1},{81,27,9,3,1},{256,64,16,4,1},{625,125,25,5,1}),CHOOSE(MATCH(B$1,{"Low (%)","Mid (%)","High (%)"},0),{-0.0625,0.7083,-2.6875,4.5417,-2.5},{-0.1667,2,-8.0833,13.25,-7},{-0.0208,0.375,-1.7292,2.875,-1.5})),1)
