In addition to what Andy already told you.

Another way to achieve the same is to call the childform WITH a reference to the form that actually did call it, as in:

Do Form ChildForm With Thisform

In the INIT of the childform I would then put this code

LPARAMETER toParentForm

this.AddProperty('oParent', NULL)

if vartype( toParentForm) == "O"
   this.oParent = toParentForm
endif

If you want a reference to the childform IN the parentform you can do it like:

LOCAL lnNewLen
If NOT pemstatus( thisform, "aChildArray",5)
   thisform.addproperty("aChildArray[1]")
endif

lnNewLen = Alen( thisform.aChildArray,1)+1
dimension thisform.aChildArray[lnNewLen,2]
Do Form ChildForm With Thisform name thisform.aChildArray[lnNewLen,1]
thisform.aChildArray[lnNewLen,2] = "MyJustCalledChildForm"

The above code should go into the place where you actually call the childform. (Buttonclick or whatever).
By using the second column you can call multiple childforms and still distinct them from each other, provided you give them separate names of course.
The above code snippets combined makes it possible for the childform to access aome properties and/or methods on the parentform.
