a2..c2 are columns of numbers. a1..c1 are accounts. i want a formula in
column d, beginning in row 2. the formula will return the value in row 1 and
column "x" where "x" is the column that has the maximum row value for any
given row.

example:

a1..c1 = 6001, 6002, 6003 respectively.
a2..c2 = $5, $0, $0 respectively.
the formula in d2 will return 6001.
