Return header for column value is found in

[47Problem]

Have found solutions when it is known what row a value is one but what I am looking for is searching 4+ columns in a table to determine the header of the column in which the value resides. Example(s): 9 = "Guest Circuit ID", 7 = "Primary Circuit ID", 2 = "Backup Circuit ID"

Ultimately this would be best if tied into results in a pivot table so assigning a value using Name Manager might next practical step once it is determined how to find value. I thought an index/match would solve this issue but have been unable to make work. Cells will be alphanumeric as well and may include symbols.

Primary Circuit ID	Backup Circuit ID	Guest Circuit ID	Primary Router Name
1	2	3	4
7	8	9	10
13	14	15	16
19	20	21	22

Match can only search one dimension, sumproduct will work here if each term doesn't repeat.

e.g.:

Excel 2010
	A	B	C	D	E	F
1	Primary Circuit ID	Backup Circuit ID	Guest Circuit ID	Primary Router Name
2	1	2	3	4
3	7	8	9	10
4	13	14	15	16
5	19	20	21	22
6
7
8					9	Guest Circuit ID

I think that is definitely headed in the direction that I need however 'sumproduct' will not work with alphanumeric will it? I have updated the table in the quoted area below with better references (should have used more realistic values to start with).

'sumproduct' will not work with alphanumeric will it?

It will
