Folks,
We were setting up a Marketing Campaign here at SierraCRM and found a bug when Selecting a Marketing Query for a new Campaign.
If you create a Marketing Campaign and instead of Creating a new Marketing Query, you choose an existing one - Save2.php threw a fatal error. We found the problem to be in /modules/MKT_Marketing/metadata/detailviewdefs.php

We are sending out a notice to all customers with the updated file.

Thanks
