Problem Using a multible member file that is in 2 libraries

I don't usually use EXTFILE or EXTMBR, so maybe there is something I'm
missing. I keep encountering a level check when I try to open any one of
these file. Could it be because of the record formats don't match
between the temp files and the files I'm trying to override them to?
