Abstractions (with replacable arguments) in Max 8.3.1

I am trying to save an abstraction to use it again and I store it in documents/Max/patches. When I open a new patcher and create an object with the name of my stored object, Max cannot find it (new object is bicolored brown). I found that the sample object in Tutorial 15.Abstractions are stored in the Max.app-package and I copied my abstraction into the same folder. Now Max finds it. But I also have a replaceable argument in my object. So now I try to use this by adding an argument to the patcher, but inside the patcher the argument stays as "#".

Any idea what I am doing wrong, I thought the document/Max/patches folder should be in Max's search path, or?
Thanks for help
