Hi

I've got an array:

A B C D
0.141823256 0.742925121 0.851363101 0.595020487
0.458170723 0.170578213 0.780241568 0.500781951
0.781171057 0.524171642 0.027494503 0.053290996
0.992753237 0.470996446 0.236928742 0.28520641

I'm looking for a formula to search the entire array (A:D) for the lowest value, and return the column name in which the value lies, e.g. the bold 0.027494503 in column C, if it is the lowest value in the array, the cell in another column (say E) needs to just say "C"

Please help! TIA
