equation to output 'name', "COPY", or "NOT FOUND"

[oprik]

Hello,
I had an excel test that I didn't do particularly well on, but this one question had me stumped.
		I need an equation that takes the name in this list and out puts the agent name in 'first.initial' or "COPY" or "NOT FOUND"
Sheet 1:		Convert these names:	Correct output:
Agent		David Everit		David.e
		Joe a.		Joe.A
Adam.m		Ben		Ben.B
		Sam p.		NOT FOUND
Agent		Training 22		Training.22
		David E.		COPY
David.e		Kat Cathy		Kat.C
		David D.		NOT FOUND
Agent		Adam.S		NOT FOUND
Joe.A
Agent
Ben.B
Agent
Kat.C
Agent
Training.22
Agent
Admin
Agent
Training.22
The equation i submitted that my teacher said was wrong was:

<colgroup><col><col><col><col><col><col></colgroup><tbody>
</tbody>

=IFNA(IF(COUNTIF(Sheet1!A:A, A3)>1, "Duplicate", INDEX(Sheet1!A:A,MATCH(A3&"*",Sheet1!A:A,0))),"Not Found")
