@else not working correctly

I followed the details exactly, and even used my text editor to validate the code. Still not working in the workspace. Don't know how to fix it. 

// Create 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;
      }    
    }    
  }
}

Looks like your else if conditions are nested in the first if.

Cheo R, Thanks for the catch. Now I've got a new error.

error scss/utilities/_mixins.scss (Line 57: Invalid null operation: "null lt null".)

// Create Media Queries

@mixin mq($break) {
  $value: map-get($breakpoints, $break);
  $sm: map-get($breakpoints, 'sm');

  @if $value < $sm {                           // LINE 57 IS HERE
    @media (max-width: $value) {
      @content;
    }
  }
  @else {
    @media (min-width: $value) {
      @content;
    }
  }
}

SOLVED:

The problem was that my breakpoints in the variables were still showing the old values.

SHOWING WRONG: 

// Breakpoints
$breakpoints:(
  'xs': 575px,  
  's': 576px,
  'm': 768px,
  'l': 992px,
);

FIXED: 

// Breakpoints
$breakpoints:(
  'xs': 575px,  
  'sm': 576px,
  'med': 768px,
  'lg': 992px,
);
