My first question is I want to lookup multiple values in the worksheet. In my
specific problem, I want to lookup three and four cells to find their matched
resultant cell.
For three lookups:
I have in one cells type of products, in second the manufacturers of that
products and in the last their capacities. How can I get the product
dimension.
A B C D
Type Manufacturer Capacities Dimensions
1 Steam Fired York 1000
2 Steam Fired York 2000
3 Steam Fired Carrier 1000
4 Steam Fired Carrier 2000
5 Steam Fired Trane 1000
6 Steam Fired Trane 2000
7 Electrical Carrier 2000
8 Electrical York 2000
9 Electrical Carrier 1000
10 Electrical Carrier 2000
11 Electrical Trane 1000
12 Electrical Trane 2000

I have used INDEX formula nested with MATCH as:

=INDEX(A1:D12,(MATCH(E1,A1:A12,0)*MATCH(F1,B1:B12, 0)*MATCH(G1,C1:C12,0)),4)

This formula give to me right answer till 4 rows, after that either it gives
random values or error.

My second question is I want make list through validation in cells E1, F1
and G1 in such a manner that when I select from the list one of the types, it
give me the manufacturers of selected type of equipments. After selection of
both type and manufacturer, it gives their matched capacities as every
manufacturer and type have different capacities.

Please help me to find the solutions,

Regards,
Zubair
