Excel | Index Match |

I require your assistance on the following:

Lets say we got 3 different groups: (A,B,C)

And we have a few value ranges within each group: 

(Eg. A has 0 - 100, 101 - 200 while B has 0 - 200, 201 - 400 and C has 0 - 300, 301 - 600.)

At the end, for each group that falls under whatever range they have, they will be assigned a final number. (Eg. 

[A,95] = 0.5 / [A,101] = 1.0
[B,95] = 1.5 / [B,205] = 3.0
[C,95] = 4.5 / [C,308] = 6.0)

Currently i have my index match formula as follows:

"=INDEX(finalnumber!F2:F29,MATCH(C11&C25,Group!A2:A29&valuerange!D2:D29,0))"

I keep getting a #N/A response.

I have also created an array table as follows:

enter image description here

Group    Range    Final Number
A        0 - 100      0.50
A        101 - 200    1.00
B        0 - 200      1.50
B        201 - 400    3.00
C        0 - 300      4.50
C        301 - 600    6.00

Pls help! Many thanks in advance!

You can use the following (you will need to tailor to your layout). I have assumed A and 95, for example, are in separate cells as you concatenate cells in your formula to do your lookup.

=IF(AND(ISERROR(INDEX(OFFSET(INDEX(C:C,H2),,,I2-H2+1,1),MATCH(VLOOKUP(G2,LEFT(OFFSET(INDEX(B:B,H2),,,I2-H2+1,1),FIND("-",OFFSET(INDEX(B:B,H2),,,I2-H2+1,1))-1)*1,TRUE),LEFT(OFFSET(INDEX(B:B,H2),,,I2-H2+1,1),FIND("-",OFFSET(INDEX(B:B,H2),,,I2-H2+1,1))-1)*1,0))),INDEX(A:A,COUNTA(A:A)+1)=F2,G2>=1*LEFT(INDEX(B:B,COUNTA(A:A)+1),FIND("-",INDEX(B:B,COUNTA(A:A)+1))-1),G2<=1*RIGHT(INDEX(B:B,COUNTA(A:A)+1),LEN(INDEX(B:B,COUNTA(A:A)+1)) - FIND("-",INDEX(B:B,COUNTA(A:A)+1)))),INDEX(C:C,COUNTA(A:A)+1),INDEX(OFFSET(INDEX(C:C,H2),,,I2-H2+1,1),MATCH(VLOOKUP(G2,LEFT(OFFSET(INDEX(B:B,H2),,,I2-H2+1,1),FIND("-",OFFSET(INDEX(B:B,H2),,,I2-H2+1,1))-1)*1,TRUE),LEFT(OFFSET(INDEX(B:B,H2),,,I2-H2+1,1),FIND("-",OFFSET(INDEX(B:B,H2),,,I2-H2+1,1))-1)*1,0)))

This is entered as an array formula with Ctrl+ Shift+ Enter

Formulas in helper cells (to keep overall formula more legible):

H2 is =MATCH(F2,A:A,0) ' finds the first match for the letter e.g. A

I2 is =MAX(IF(A:A=F2,ROW(A:A)-ROW(INDEX(A:A,1,1))+1)) ' finds the last match for the letter e.g. A. This is entered with Ctrl+ Shift+ Enter i.e. an array formula.

Notes:

You might want to wrap the whole thing in an IFERROR( formula, "") to hide any not found error messages.

I'm unclear why you require four separate worksheets for this operation. For simplicity in demonstrating, I've put your lookup table on the same worksheet as the values to lookup.

=SUMPRODUCT(I$2:I$7, (G$2:G$7=LEFT(A2))*(--REPLACE(H$2:H$7, FIND(" - ", H$2:H$7), 9, TEXT(,))<=--MID(A2, 3, 9))*
                                        (--REPLACE(H$2:H$7, 1, FIND(" - ", H$2:H$7)+1, TEXT(,))>=--MID(A2, 3, 9)))
