Element.GetParameterValueByName not working

I use dynamo 1.3 on windows 7
I’m trying to get the height of my windows by Element.GetParameterValueByName
But I get a list WITHOUT VALUES.
I tried many parameter names (normally the three of them are correct), I tried also the LunchBox,
I have the same problem with walls.

Do you know where is the problem?
Their is another function that I can use instead?

You try to find the Hight of the host element, not of the Windows,

and the hight of the Window is a typeparameter.
Try this:

It worked, so for height standard name "Height " won’t work all the time.
Thank you too much
