Maybe I can clarify. You are right, BIZ object belongs to the form which is UI. BIZ object is instantiated in the INIT method of the UI form. And when BIZ object is instantiated, in its (BIZ) INIT method it instantiates the DA object. Passing THISFORM (UI) to the BIZ on instantiation allows the BIZ get some values from properties of the UI form. And then BIZ passes itself (THIS) to the DA object on instantiating. And DA can now get values of the BIZ object properties. Does the above makes it more clear? <g>.
