Trying the code below to pass this Sass mixin exercise, but I’m stumped as to why it fails.

  @mixin border-stroke($val){
    @if $val == light{
      border: 1px solid black
    }
    @else if $val == medium{
      border: 3px solid black
    }
    @else if $val == heavy{
      border: 6px solid black
    }
    @else {
    }
  }

Any help would be appreciated.

You forgot border: none;

Thanks! I also missed all the semicolons. Challenge passed.
