[gme-users] how to connect atoms in different models

[Nicki Lehmann Møller]

Hi Akos and Christian,

Thanks a bunch. I got it to work once I deleted my current aspect (and used
the default) and made the connection go through the reference just like
Christian stated (Sorry Christian for not listening :))

Thanks to you both.
