ruby on rails 3 - Foundation Variables Undefined -

I am a little embarrassed, I can not understand it. For example, whenever I refer to a foundation variable in my scss sheet, I get an error.

Undefined variable: "$ primary-color" (in /my/path/to/mysheet.scss)

My app here. SCSS

  / * * = Need_self * = require_tree ./a_folder * / @import "Foundation / Foundation-Global"; @import "Foundation / _Settings"; @import "foundation";   
 I doubt because  import  s is required after  s  but when I cancel the order, all my stylesheets Disappears.  
 What am I doing?   
 
 
 I got the same status in the bootstrap. If using , , all the variables can not be used on custom CSS files.  
 The solution is to use  @import  but at any  .  
 I suggest that you need to  need , and  @import  to manually remove the  application from your custom CSS files . Css.scss .  @import  will also work for the asset pipeline, so do not worry, just type a few words.
