Thanks Baz, that one helped me out. I didn't get it into my grey cells that keyName = googleKey. Of course, it's not a problem to use a kind, but I didn't know that you can use a GoogleKey as a KeyName to update an object with GoogleWrite.
Great, let's put my model together this night! Thanks again Baz. Rainer.
