As Matt suggested, you can use the reference to the calling form.

From the parent form you would do something like:

DoForm("PhaseForm", ThisForm)

Of course, you will have to put code in the init of PhaseForm to accept the parameter. For example:

LPARAMETERS toCallingForm

This.oCallingForm = toCallingForm

Then, in your PhaseObj1.cParentBizObj property place the reference to the ProjectObj1 via the oCallingForm property.
