Code challenge don't know what i'm doing wrong :(

Switch the order of the arguments. Be sure to specify the variable for each argument, or you'll wind up with a height and width of 'red' and a '1px solid 10px' border! (Needless to say, that would be invalid.)

here is my code :

/* Write your SCSS code below. */

@mixin square($size, $color:black) {
    width:$size
    height:$size
    border:1px solid $color
}
.box {
    @include square($color: red, $size: 10px);
    }

Try this: 

@mixin square($size, $color:black) {
    width:$size;
    height:$size;
    border:1px solid $color;
}
.box {
    @include square( $color: red, $size: 10px);
    }
