SCSS @media compile error

I'm using Prepros to compile my SCSS files to CSS, but it gives me an error when i try to use media queries. I tried Coala and Scout as well. If i just copy this code into output CSS it works. What am i doing wrong?

@media only screen and (max-width: 320px) {
  body {
    width: 320px;
  }
  .wrapper {
    width: 320px;
    margin: 0 auto;
  }
  .works-wrap {
    width: 320px;
  }
}

@media only screen and (min-width: 320px) and (max-width: 610px) {
  .wrapper {
    width: 320px;
    margin: 0 auto;
  }
  .works-wrap {
    width: 320px;
  }
}

@media only screen and (min-width: 610px) and (max-width: 950px) {
  .wrapper {
    width: 650px;
    margin: 4% auto;
  }
  .name {
    width: 100%;
  }
  .works-wrap {
    width: 650px;
    margin-left: 10px;
  }
}​

@media only screen and (min-width: 950px) and (max-width: 1024px) {
  .wrapper {
    width: 950px;
    margin: 4% auto;
  }
  .name {
    width: 100%;
  }
  .works-wrap {
    width: 950px;
  }
}

Error code:

Error: Invalid CSS after "​": expected selector, was "@media only scr..."
        on line 169 of style.scss

Try this it is a copy/paste mistake

@media only screen and (max-width: 320px) {
    body {
        width: 320px;
    }
    .wrapper {
        width: 320px;
        margin: 0 auto;
    }
    .works-wrap {
        width: 320px;
    }
}

@media only screen and (min-width: 320px) and (max-width: 610px) {
    .wrapper {
        width: 320px;
        margin: 0 auto;
    }
    .works-wrap {
        width: 320px;
    }
}
@media only screen and (min-width: 610px) and (max-width: 950px) {
    .wrapper {
        width: 650px;
        margin: 4% auto;
    }
    .name {
        width: 100%;
    }
    .works-wrap {
        width: 650px;
        margin-left: 10px;
    }
}

@media only screen and (min-width: 950px) and (max-width: 1024px) {
    .wrapper {
        width: 950px;
        margin: 4% auto;
    }
    .name {
        width: 100%;
    }
    .works-wrap {
        width: 950px;
    }
}

There is a hidden char just after the closing bracket of @media only screen and (min-width: 610px) and (max-width: 950px) just delete it
