ASP.NET MVC Razor set style attribute in foreach

I want to set the width of a div via the style Attribute (to use the div as a bootstrap progress bar. I want to do this in a foreach loop

 @foreach (var item in Items)
      {
        <tr>
          <td>@item.Name</td>
          <td>
            <div class="progress">
              <div class="progress-bar" role="progressbar" aria-valuenow="@item.PercentageCompleted" aria-valuemin="0" aria-valuemax="100" style="width: @item.PercentageCompleted;">

              </div>
            </div>
          </td>
        </tr>
      }  `

What happens is that the style attribute is empty. Is there a way to achieve this?
