Answer 1

Start of with a class

Public Class Product
    Public Property Name As String
    Public Property Cost As Decimal
End Class

Get the sum of cost

Dim Products As New List(Of Product) From
    {
        New Product With {.Name = "Item1", .Cost = 12D},
        New Product With {.Name = "Item2", .Cost = 10D}
    }
Dim CostSum = Products.Sum(Function(p) p.Cost)

CostSum = 22

The red box over the tooltip contains your hint...

You need to provide a function which takes an instance of tblEventSStaffRequired and returns a Decimal value.  Karen has provided an example of what such a function might look like.
