Hi Peter,

I'm not sure where the problem is but in this case it would be logical to pass an object as a parameter to the oClassPicker. Something like

* textbox InterActiveChange 
loParam = Createobject("custom")
loParam.Addproperty("ReturnValue", null)
oClassPicker = Newobject("...", "..", "", loParam )
oClassPicker.Show(1) 
This.Value = loParam.ReturnValue

* VarPicker Init 
LPARAMETERS toParamObj
This.oParamObj = toParamObj

* VarPicker Unload
This.oParamObj.ReturnValue = Thisform.Listbox.Value
This.oParamObj = Null
