Preventing Invalid Operation in Compact/Repair MS access

Hi,

Is there anyone here has Idea that if im Compacting/repair or Creating Mde it always give me msgbox of Invalid Operation?

Did I miss something here? Is it on the reference I checked inside VBA? coz before I can compile my database but now cannot.

Thanks!

There should be no reference needed if doing the C&R from within Acess' menu item.
