Non puoi mettere This,Thisform dentro un EXECSCRIPT()

Usa questo:

...
WITH m.thisForm
  =EXECSCRIPT(memoScript)
ENDWITH

e in memoScript
sostitituisci thisform.XXXXX con .XXXXX

Ma se hai una espressione allora

=EVAL(memexpression)

viene eseguita nel contesto dell'oggetto, e puoi lasciare Thisform

You cannot put This, Thisform within a EXECSCRIPT()

You can to use this:

...
  WITH m.thisForm 
    = EXECSCRIPT(memoScript)
   ENDWITH 

and in memoScript replace thisform.XXXXX with XXXXX

But if you have an expression

= EVAL(memexpression)

comes executed in the context of the object, and can leave Thisform within it.
