INDEX/VLOOKUP Forumla for Unique List

[MJLG85]

Hello

So I have manged to find a formula to help produce a list of unique names based on rules, but i can only get it to return the first name from the whole list.

{=IFERROR(INDEX(Master!$B$2:$B$500,MATCH(0,COUNTIF(H$2,IF(Master!A$2:A$500=H$2,Master!B$2:B$500,H$2)),0)),"")}

"Master B" is the range i want the names from
H2 is the name/value i want it to check in Master A

I then did th ctrl+shift+return trick, dragged it dwn but only the first name appears when i know there are more, yet al th sites i have looked at shows i will return the next name that matches H2

Should i be using Vlookup in this to help it?

How about
=IFERROR(INDEX(Master!$B$2:$B$500,AGGREGATE(15,6,(ROW(Master!$B$2:$B$500)-ROW(Master!$B$2)+1)/(Master!A$2:A$500=H$2),ROWS($H$3:$H3))),"")
