Pattrstorage's used slots number

izhak2's icon

Hello,

How is it possible to get the used slots number of a pattrstorage?
I didn't succeed to get the "getslotlist" message to work..
I connected it to the left inlet of pattrstorage, and connected a print object to its left outlet output (dumpout) and nothing came up in the Max Window.

How to get that work?

Thanks in advance.
