Thanks very much... that should have been obvious to me.
Now, however, the error I'm getting is Unknown column 'UNIX_TIMESTAMP' in 'where clause'.
I would think that the WHERE clause is keying off fld_approved within the parens, but apparently not.
I've tried WHERE((fld_approved + 259200) < UNIX_TIMESTAMP) and other variations which would force the identification of fld_approved, but without any luck.
