How Retrive And Store Attribute Names

Member Posts: 1

Hi All,
I'm trying to loop over attributes using "Loop Attributes" and I need to Store Attribute Name whose value is higher than others in the new Attribute "target_stock_name".
Using %{loop_attribute} variable inside loop I can obtain just current attribute value, but NOT the relative name that I need to store.
Thanks for your help
Diego
That's my incomplete code:
