Match a value, retrun correspond, if matche are more then one, retrun largest correspond

Hi , i have a sheet which contain data like this

a b c d e f g
1 0.014 0.55 0.27 0.9 0.05 0.31
2 9 5 0 9 9 5
3
4
5
6
7
8
9
0

now, if the content of a1 (1) is met into the $b$2:$g$2 then
i would like to get the correspond value from $b$1:$g$1
into h1 and so on till h10

in this sheet b2, d2 & f2 contain same value but the
correspond are not same & in this condition i would like to
pull the largest correspond value.

If i use this formula
=index($b$1:$g$1,match(a1,$b$2:$g$2,0))
it is god for unique but when table contain duplicate
it doesn't go to 2nd or 3rd duplicate value & pulls
correspond value of 1st duplicate value.
Which is the smallest correspond.
If i use this formula =index($b$1:$g$1,large(if($b$2:$g$2=a1,column($b$2:$g$2)-column($b$1),""),1))

it gives the the largest column reference which return the
3rd correspond value which is smaller the 2nd correspond.

Instead of large() if i use small() then it gives the
smallest column ref which return the 1 correspond value
& problem remain same.

I would like to result like that

a b c d e f g h

1 0.014 0.55 0.27 0.9 0.05 0.31 n/a

2 9 5 0 9 9 5 n/a

3 n/a

4 0.31

5 0.55

6 n/a

7 n/a

8 n/a

9 0.9

0 0.27





help will be appreciated
thanks
