I deleted the field and re-added it in layout mode. If I resize the control, it puts "::" in front of the field. I got it to work but I'm not sure what happened.
It's now there but it has the following text written across it: "<Unrelated Table>"
Most likely, you have more that one occurrence of the Person table in your relationship graph; the layout is defined to show records from one of these, while the field is coming from another.
That was it. Thanks!!!!
