SIDE NOTE: don’t know if this matters but they are all ‘shared’ parameters.
It doesnt matter
.
For your errot, set keys at level 2 
Now I still get this error… Again no parameter by that name… my head is exploding! 

Dont worry
at least you are trying.
Can you give me a larger snip? where i can se the whole graph?

you’re missing Element.elementtype

test.dyn (25.9 KB)
Still the same error…
test.dyn (25.9 KB)
I download your REvit
That revit doesn’t have the all the parameters as instance parameters, I’ll upload a new one!
Error is still no parameter with that name?
indeed, I don’t get it…
This is so weird… Why is it not working for me? There is obviously a parameter with that name cause it works for you… 
Yeah I can do a lot apparently but for some reason it doesn’t work and I get an error, but you do the exact same thing and everything works? How is it possible?
Can you view the results of each node?
I notice now that the parameter is not visible in my type properties, but when I edit the family it is in fact an instance parameter? What should I do?
