explanation: i facing some syntax errors while running progranm and overcome through shown by command window and for loop ,multiplication symbols  and then clear errors  runnig my programm result has come but not shown in my folder then go to one on one session and some errors in movie coding like put % symbol before movie codings and capital letters like v,w finally sort out by one on one session

thank yoy
