How to determine if custom objects have been enabled for my sandbox
Under Admin, Database Management, Marketo Custom Objects, I've managed to create a few test / sample objects. I'm trying to link these objects back to the lead or account objects, but I do not see the option where I can link the fields. The documentation shows a screen where you can link the object via a link field. My screen doesn't seem to have such an option.
How can I determine if custom objects have been enabled for our sandbox? I suspect that's why I'm not able to see the link info.
Thanks in advance,
Dan
