match 2 colomns to give result

I am trying to get a result by matching 2 spreadsheets ,so sheet2 match trid and btn to sheet1 and give result match.
sheet1

A B
trid btn
1 75
2 22
2 540

Sheet2
A B C
trid btn
1 20
2 86
2 45
2 540 Match

Put this array formula in C2 and copy it down:

=IF(ISNUMBER(MATCH(A2&"-"&B2,Sheet1!$A$2:$A$20&"-"&Sheet1!$B$2:$B$20,0)),"Match","")

...that is an array formula, so confirm it with CTRL-SHIFT-ENTER to activate the array. If you just press ENTER it will not work, press F2 on the cell and then CTRL-SHIFT-ENTER to correct.

Non Array

C2: =REPT("Match",ISNUMBER(MATCH(1,INDEX((Sheet1!$A$1:$A$100=$A2)*(Sheet1!$B$1:$B$100=$B2),0),0)))

copy down as required
