231,275 PointsYou did add a second parameter, just not the right one.
The challenge tells you that a collection of select list items "is available via the ViewBag.DepartmentsSelectListItems
property." You should use that as the second parameter of Html.DropDownListFor instead of "SelectListItems".
It also says this collection is "of type SelectList
", so you might need to use a cast so they are interpreted as the proper type for the function.

20,485 PointsHere's what you need. I'm new too and don't always understand all the jargon people give in their answers. But I figured it out.
<div>
@Html.LabelFor(m => m.DepartmentId)
@Html.DropDownListFor(m => m.DepartmentId, (SelectList)ViewBag.DepartmentsSelectListItems)
</div>
