Well, I'll give you a start, if I can:

First, your tables will need to have a primary key defined.

Then in the Trigger boxes, call these procedures:

PROC CopyUpdate
LOCAL llReturn

SELECT MyTable2  && assume order set to PK
SEEK MyTable1.PK
IF FOUND()
  REPL Field1 WITH MyTable1.Field1, ; 
       Field2 WITH MyTable1.Field2, ;
       Field3 WITH MyTable1.Field3, ;
       Field4 WITH MyTable1.Field4
  llReturn = .T.
ELSE
  llReturn = .F.
ENDIF

SELECT MyTable1

RETURN llReturn

PROC CopyInsert

INSERT INTO MyTable2 ( PK, Field1, Field2, Field3, Field4) ;
       VALUES (PK, Field1, Field2, Field3, Field4)

RETURN .T.

PROC CopyDelete
LOCAL llReturn

SELECT MyTable2  && assume order set to PK
SEEK MyTable1.PK
IF FOUND()
  DELETE
  llReturn = .T.
ELSE
  llReturn = .F.
ENDIF

SELECT MyTable1

Obviously, you'll need code for buffering and messaging, but that should give you an idea.
