Not having figured out how to use the cascaded "Combo Box" controls yet, in the form fRequest you must enter the following event:
Code:
Private Sub Form_Current()
Me.cboBrand = DLookup("BrandID", "tblDevices", "DeviceID = " & Nz(Me.DeviceID, 0))
Me.cboDeviceType.Requery
Me.cboDeviceType = DLookup("DeviceTypeID", "tblDevices", "DeviceID = " & Nz(Me.DeviceID, 0))
Me.cboDevice.Requery
End Sub
but you keep making mistake about mistakes, see: in the fRequest there are the cboFacility, cboBuilding, cboWing, cboFloor, cboLocation "Combo Box" controls which make no sense as they do nothing. The Required property is hardly ever used correctly by setting it to Yes where the data is needed.
