Removing duplicates in Index match results

Hi
Hopefully someone will be able to assist with this... because it's driving me mad.
I have a summary sheet called Targetted where I am trying to collate results, currently I am using the small function with criteria to pull the lowest values for each sales agent this pulls from a separate sheet called Rev 3
 {=SMALL(IF('Rev 3'!$G:$G=Targetted!$B$3,'Rev 3'!$AH:$AH),Targetted!A56)}
Rev 3 Column G is the agent name
Targetted B3 is agent name
Rev 3 AH is the value
Targetted A56 is the rank
This formula works fine and pulls the lowest 20 results
I then use the following formula to pull through the relevant company name
{=INDEX('Rev 3'!$B:$B,MATCH(1,('Rev 3'!$AH:$AH=G56)*('Rev 3'!$G:$G=Targetted!$B$3),0))}
Rev 3 column B is the company name
G56 is the result from the small function.
The issue I have is that the result for the company where I have the same value on more than one row is always the first company name the formula finds.
Any help would be greatly appreciated.
