SetParameterByName for Multiple Parameters for Multiple Elements of one Category

I have seen many posts on this topic, but nothing could work well for me.
In attached image, i have been trying to achieve setparametervaluebyname for multiple elements of same category (air terminals).
SInce inputs “Elements” and "ParameterName are both “list of list”, whereas the “Value” is “list of list of list”. I have tried multiple options of levels as well as lacing. Nothing is working.

Need help…

@walzworld Try with these levels on longest lacing:
