import appuifw
 
class MyFormView( object ):
    
    ## The constructor.
    def __init__( self ):
        ## Bool
        self._iIsEdited = False
        self._iFields = [( u'Amount1','number', 5 ),
                         ( u'Amount2','number', 5 ),
                         ( u'Amount3','number', 5 ),
				 ( u'Total','number', 5 )]
 
 
    ## Displays the form.
    def setActive( self ):
        self._iIsEdited = False
        self._iForm = appuifw.Form(self._iFields, appuifw.FFormDoubleSpaced)
        self._iForm.save_hook = self._markEdited
        self._iForm.flags = appuifw.FFormDoubleSpaced
        self._iForm.execute( )
 
 



    def _markEdited( self, aBool ):
        self._iIsEdited = aBool
	
         

    def isEdited( self ):
        return self._iIsEdited

    def abc(self):
	  self._iForm[3][2]=self._iForm[0][2]+self._iForm[1][2]+self._iForm[2][2]


   
 
if __name__ == "__main__":
    appuifw.app.title = u'Try Forms'
    myForm = MyFormView( )
    myForm.setActive( )
    
    if myForm.isEdited( ):
        myForm.abc()

Now it gives me error,

self._iForm[3][2]=self._iForm[0][2]+self._iForm[1][2]+self._iForm[2][2]

Object doesn't support iten assignment

Now Can something be done here?

hi shubhendra

the below line mentioned by you will definitely give error,Object doesn't support iten assignment

self._iForm[3][2]=self._iForm[0][2]+self._iForm[1][2]+self._iForm[2][2]

just make one simple change :
Total=self._iForm[0][2]+self._iForm[1][2]+self._iForm[2][2]
and call this "Total" variable at new form execution.
It should work.
