Set source of Control Box to Subform (1 Viewer)

[Tina49]

I have a subform called DD subform
I have an unbound combo box named Target
How to I set the control source of Target to reflect my DD subform?

In control source, my only choices are the fields related to the subform, not the subform itself.

I'm not sure I understand the querstion. The RowSource of a combo is either a hard-coded list, the name of a table, the name of a query, or an SQL string instead of a query. It can't be a subform. A subform isn't a list of data.
