Help with media queries

@mixin mq($break) {
   @if $break == 'xs' {
     @media (max-width: $break-xs) {
       @content;
     }
   } 
   @else if $break == 'sm' {
     @media (min-width: $break-s) {
       @content; 
   }
  }
  @else if $break == 'med' {
     @media (min-width: $break-m) {
       @content;    
   }     
  }
  @else if $break == 'lg' {
     @media (min-width: $break-l) {
       @content; 
    }
  }
 }

It says error: 

undefined variable: "$break-m"
on line 60 of scss/utilities/_mixins.scss, in 'mq' 
from line 8 of scss/layout/_containers.scss

Where are you declaring your $break-{} variables? Is $break-m spelled correctly and defined? It can't find a reference indicating there is some issue where this code is located.
