SASS Error With Variable Interpolation

[timothydungan]

I know this addon was built for Sublime Text 2, but I'm using it in ST3. I'm hoping someone can spot the problem here, because this works just fine in ATOM. I call the SASS mixin below with a standard INCLUDE, (@include transition(box-shadow 600ms ease);) but the build throws an error at the very first variable interpolation.

@mixin transition($prop, $values...) { -webkit-#{$prop}: $values; -moz-#{$prop}: $values; -ms-#{$prop}: $values; -o-#{$prop}: $values; $prop: $values; }
