Excel repeatedly shows the same name

Hi all. I'm a new member here.
I have a problem with my formula. As you can see, i want to get the CIM number of the Team Leaders (TL Name) when i change the dropdown list of the campaign. But what im getting is the repeated CIM numbers.

Here's my formula:

=IF(ISERROR(INDEX('Team Data'!$F$2:$F$5489,SMALL(IF('scorecard (OM Search)'!$C$12='Team Data'!$E$2:$E$5489,ROW('Team Data'!$E$2:$E$5489)-MIN(ROW('Team Data'!$E$2:$E$5489))+1,""),ROW(A1)))),"",INDEX('Team Data'!$F$2:$F$5489,SMALL(IF('scorecard (OM Search)'!$C$12='Team Data'!$E$2:$E$5489,ROW('Team Data'!$E$2:$E$5489)-MIN(ROW('Team Data'!$E$2:$E$5489))+1,""),ROW(A1))))


Please help..
