Compare Excel spreadsheet - 1

I have 2 spreadsheets in the same workbook.

In spreadsheet 1, column B and C, I have list of user First and Last Names:

First Name      Last Name
John            Doe
Mary            Dawson
Rob                    Cool
Ivan            Dyals


In spreadsheet 2, column K and L, I have list of user First and Last names:

First Name      Last Name--->this is in row 2
Mary            Dawson
Anthony            Fusco
Jack                    Palermo
Rob                    Cool
....

I want to column M of spreadsheet 2 to show MATCH if name is found in spreadsheet 1:

First Name      Last Name
Mary            Dawson            MATCH
Anthony            Fusco            
Jack                    Palermo            
Rob                    Cool            MATCH
....

I am using the below similar to what another expert suggests in M3 of spreadsheet 2 but it is not working.  

=IF(ISERROR( MATCH(L3 & ", " &K3,Sheet1!F:F,0) ), "", "Match")

Please advise in this ticket.  Thanks.
