In the builder of ProgroutinObj, under the Parent/Child setting, Parent object is ProgrammersObj which is present on page1. In the intial selected alias Tab, I selected Requery if parent changes. With this settings I get the error, but if I change the settings in the initial selected alias tab to Don't auto query then it doesnot give me error but shows me blank grid.

This is happening everytime I select page 3 and never got the chance to add the record
lnewChildOnNewParent for ProRoutinObj is False

Thanks
