Unable to write cache folder for smarty project on pagodabox-Collection of common programming errors

I have created project in smarty and now i am trying to host it on pagodabox.com. I have created application on pagodabox.com and uploaded all code on to this application but problem is this now i am unable to configure cache and compiler directory in pagodabox.com that’s why it output fetal error because cache and compiler directory is read only mode. I have try Boxfile to resolve this issue but failing to solve. I am not aware how i can make these directory writable. please help me. this is url of project http://moviestock.pagodabox.com/ and following is my Boxfile configuration

web1: #component type & number
  name: blog            #component settings
  shared_writable_dirs:
    - var/secured/cache
    - var/secured/compiler
    - var/sessions
  document_root: app
  php_version: 5.3.8

and i am getting this following error :
