14,583 Pointswhy am I getting this error in the css output?
Error: Undefined variable: "$target".
@for $i from 1 through $g-col-count {
$context: g-context($g-col-width, $g-col-count, $g-gutter-width) !global;
$target: ($g-col-width * $i) + ($g-gutter-width * ($i - 1));
.grid__col--#{$i} {
width: percentage( $target / $context );
}
}
