MDI children cannot have MDI children of their own. There can be only one MDI parent form in an application. All MDI children in a program are necessarily children of that one MDI parent. > WITHOUT having to include the MDIForm in the > uses clause of the MDIChild-of-a-MDIChild.

To do that, you'll need to include the TMDIForm class's unit in one of the calling unit's "uses" clauses. > MDIChild2 --> MDIChild1 --> MDIForm(CurrentTable) > > Thanks in advance for your help :) -- Rob
