Getting the name of minimum-value attribute

Hi,
Suppose I have an exampleset with five attributes att1, att2,....att5. Now, I want to create a new attribute "Group", which contains the attribute names, corresponding to the minimum of the values of att1,...att5.
Example:
att1 att2 att3 att4 att5 Group
1 3 4 -4 2 att4
31 0 1 2 8 att2
-10 4 1 12 5 att1
How do we do this? Or instead of "Group", even just the numbers would also be fine. Like instead of att4, att2,att1 in the above, if one get 4,2,1 that should also be fine.
I have here with attached a code:
