i have the following given :

A B
1 asih 234
2 aa 334
3 bb 434
4 asih 534
5 cc 634
6 dd 734
7 asih 834

i managed to do the following :
{INDEX($A$1:$B$7,SMALL(IF($A$1:$A$7=C1,ROW($A$1:$A $7)),ROW(1:1)),2)}
and i dragged it to cell C3.
NOW.....
my purpose for this is to be able TO enter the word "asih" in C1 and C2 and
C3 in order to be able its coresponding data which are : 234 , 534 , 834
MY QUESTION NOW IS :
what should i do to insert the following formula : index(....),match(....) )
WITHIN THE PRECEDENT FORMULA:
{INDEX($A$1:$B$7,SMALL(IF($A$1:$A$7=C1,ROW($A$1:$A $7)),ROW(1:1)),2)}
AND THAT IN ORDER TO GET FOR EXAMPLE (734) IF I HAD TO TYPE (DD).????

THANKS FOR YOUR HELP
