C# ASP.NET MVC Forms Improving Our Form Drop Down Lists

Am I calling the Htlm.DropDownListFor method incorrectly?

Every time I hit Check Work I am met with a response of:

"Bummer: Did you replace the 'DepartmentId' field's Html.TextBoxFor method call with a call to the Html.DropDownListFor HTML helper method?"

Can anyone spot an obvious, silly mistake that I'm making?

Report.cshtml 
@model IssueReporter.Models.Issue

@{
    ViewBag.Title = "Report an Issue";
}

<h2>@ViewBag.Title</h2>

@using (Html.BeginForm())
{
    <div>
        @Html.LabelFor(m => m.Name)
        @Html.TextBoxFor(m => m.Name)
    </div>

    <div>
        @Html.LabelFor(m => m.Email)
        @Html.TextBoxFor(m => m.Email)
    </div>

    <div>
        @Html.LabelFor(m => m.DepartmentId)
        @Html.DropDownListFor(m => m.DepartmentId, (SelectList)ViewBag.DepartmentsSelectListItem)
    </div>

    <div>
        @Html.LabelFor(m => m.Severity)
        @Html.TextBoxFor(m => m.Severity)
    </div>

    <div>
        @Html.LabelFor(m => m.Reproducible)
        @Html.TextBoxFor(m => m.Reproducible)
    </div>

    <div>
        @Html.LabelFor(m => m.DescriptionOfProblem)
        @Html.TextAreaFor(m => m.DescriptionOfProblem)
    </div>

    <button type="submit">Save</button>
}

It's a spelling error, the instructions say to use ViewBag.DepartmentsSelectListItems (plural) but this code has "ViewBag.DepartmentsSelectListItem" (singular).

Thank you once again Steven. I knew it was a silly mistake.
