I tried this:

DO CASE
   CASE ... = 'EDIT'
       IF ISRLOCKED()
           MESSAGEBOX('BLA BLA BLA')
           RETURN
       ENDIF
       *** EDIT STUFF   
   CASE ... = 'SAVE'
      *** DO THE SAVE STUFF
ENDCASE

But that is not working either.
I have this method called set_errors() that is a method of my oApp class.
But I set it off by saying ON ERROR so I can Get the default Error Message for this segment of code.

I Don't know what to do now.
