Group rooms by Department and return the totals to a parameter of each room

Hi everyone, I’m really new in this Dynamo world and I’m not able to finish my first routine…
I have differents rooms with their Corresponding areas and Departments.
I’d like to have a new parameter in each room in which I could see the Total Area of the Department.

I’m collecting the rooms, getting their parameters, grouping… but now I don´t know how to transfer those totals to each rooms.

Thanks for your help (and patience)

(I know I can do a Schedule in which I’m able to group by departments… but I really like to have that data in the instance parameter)

Thanks so much. This graph with the Python script worked perfectly!
Could I have a filter by Design Option?
The final sum of the data includes all the Options that I’m working with.
Thanks again.

Thanks for your help!

I tried this graph but the result wasn’t the one that I needed.
The I tried the other option in the blog and that was perfect for my purpose.
