Can't access application value.

Hi.

I use code on config.lua


application =
{
content =
{
–zoom
width = 768,
height = 1024,
scale = “letterbox”,
imageSuffix = {
["@2x"] = 2,
}
},
— for levelHelper , you can change the value depends on your folder structure
LevelHelperSettings =
{
imagesSubfolder = “assets/sprites”,
levelsSubfolder = “assets/scenes”,
directorGroup = nil --The group where all objects will be added
},
---- for sprite helper , you can change the value depends on your folder structure
SpriteHelperSettings =
{
imagesSubfolder = “assets/sprites”,
levelsSubfolder = “assets/scenes”
},
}

when i try to access the application value such as below,

application.SpriteHelperSettings[“imagesSubfolder”]…"/"…correctStr;

Compiler said

attempt to index global ‘application’ (a nil value)
I am using 2011.715 version

Thank a lot.
