  On my Index.cshtml I'm getting "does not contain definition for 'PageIndex and no extension method for PageIndex."

  Here's the code:

  @page
  @model ContosoUniversity.Pages.Students.IndexModel
  
  @{
      ViewData["Title"] = "Index";
  }
  
  <h2>Index</h2>
  
  <p>
      <a asp-page="Create">Create New</a>
  </p>
  
  <form asp-page="./Index" method="get">
      <div class="form-actions no-color">
          <p>
              Find by name: <input type="text" name="SearchString" value="@Model.CurrentFilter" />
              <input type="submit" value="Search" class="btn btn-default" /> |
              <a asp-page="./Index">Back to full List</a>
          </p>
      </div>
  </form>
  
  <table class="table">
      <thead>
          <tr>
              <th>
                  <a asp-page="./Index" asp-route-sortOrder="@Model.NameSort"
                     asp-route-currentFilter="@Model.CurrentFilter">
                      @Html.DisplayNameFor(model => model.Student[0].LastName)
                  </a>
              </th>
              <th>
                  @Html.DisplayNameFor(model => model.Student[0].FirstMidName)
              </th>
              <th>
                  <a asp-page="./Index" asp-route-sortOrder="@Model.DateSort"
                     asp-route-currentFilter="@Model.CurrentFilter">
                      @Html.DisplayNameFor(model => model.Student[0].EnrollmentDate)
                  </a>
              </th>
              <th></th>
          </tr>
      </thead>
      <tbody>
          @foreach (var item in Model.Student)
          {
              <tr>
                  <td>
                      @Html.DisplayFor(modelItem => item.LastName)
                  </td>
                  <td>
                      @Html.DisplayFor(modelItem => item.FirstMidName)
                  </td>
                  <td>
                      @Html.DisplayFor(modelItem => item.EnrollmentDate)
                  </td>
                  <td>
                      <a asp-page="./Edit" asp-route-id="@item.ID">Edit</a> |
                      <a asp-page="./Details" asp-route-id="@item.ID">Details</a> |
                      <a asp-page="./Delete" asp-route-id="@item.ID">Delete</a>
                  </td>
              </tr>
          }
      </tbody>
  </table>
  
  @{
      var prevDisabled = !Model.Student.HasPreviousPage ? "disabled" : "";
      var nextDisabled = !Model.Student.HasNextPage ? "disabled" : "";
  }
  
  <a asp-page="./Index"
     asp-route-sortOrder="@Model.CurrentSort"
     asp-route-pageIndex="@(Model.Student.PageIndex - 1)"
     asp-route-currentFilter="@Model.CurrentFilter"
     class="btn btn-default @prevDisabled">
      Previous
  </a>
  <a asp-page="./Index"
     asp-route-sortOrder="@Model.CurrentSort"
     asp-route-pageIndex="@(Model.Student.PageIndex + 1)"
     asp-route-currentFilter="@Model.CurrentFilter"
     class="btn btn-default @nextDisabled">
      Next
  </a>

  Does anyone know how to fix this? Please explain it like I'm a 2 year old.  I'm new to this. Thank you
