Am i being silly here of should this logically work. Or cant i use a varible to check?

i have a list view of courses with faculties, and each page i am on has a drop down to select a faculty. I want to display in a dropdown on each page each course assosiated with this faculty.

@foreach (var pageCourse in @Model.Content.AncestorOrSelf(1).Children.Where(x => x.Name == "Courselist"))
 {
  foreach (var subpageCourse in pageCourse.Children.Where("Visible").Where("courseListFaculty == \"@faculty\""))
  {
    <option value="">@subpageCourse.Name</option>
  }
}

if i change the @faculty to the actual string "A Level" it works and only displays from the faculty. but i want it to be dynamic per page from the dropdown value

Thanks

David
