Set Parameter By Name Not working Properly

So, i’m trying to use the SetParameterByName in the imperative mode of coding in Dynamo.
I get as a result a list with the exact structure as i want, so i think that the problem is not in the indexes of the fors. But the list returns only null values.
It seems like the Method SetParameterByName is not working properly in the imperative mode.
Here is a picture that shows this problem.
I’m also linking the Dyn file and the Project file i used to do this.
Thank you all in advance!
