@Schorschua-Phrosch Yes, indeed. You have to use [receive openpanel] (and not [receive camomile]) to receive the file path. Here is the documentation. And here is a fixed version: Openpanel.pd.
And as it seems that you use a Windows system, you will encounter the bug 131. I recommend you to use the beta release. Here is the last ones for Windows64 and for Windows32. At last, using your patch with the plugin PdStal just reveals a new bug - it seems there is a conflict with this example.I will fix this for the next release.
