CSS Modular CSS with Sass Sass Grid System Sass Grid System Challenge

What am I missing in this @for and percentage challenge?

@for $i from 1 through $cols { .grid__col--#{$i} { $target : ($width * $i) + ($gutter * ($i -1));
width : percentage($target / $context); } }

It keeps giving me an error: invalid CSS after "width . . . .

I defined $target just like they said to, and calculate the width with the percentage. What am I missing?

Thanks!

style.scss 
div {
  background-color: green;
}

$cols    : 10;
$width   : 50px;
$gutter  : 15px;
$context : ($width * $cols) + ($gutter * ($cols - 1));

@for $i from 1 through $cols {
  $target : ($width * $i) + ($gutter * ($i -1));

  .grid__col--#{$i} {
      width   : percentage($target / $context);
  }
}

I finally figured it out. I was missing a space before the one in my $target: equation. That is 30 minutes I will never get back, but I will probably never make that mistake again. :)

I just found this wondering if the challenge was bugged or something. Somehow, I had the exact same problem. I had -1 instead of - 1. Not sure how I missed that or why I did that.
