VBA Macro To Create Multiple Data Validation Lists From Variables & Named Ranges

I cant seem to find the correct syntax for creating 14 validation lists using array members as the source of the named ranged. The validation lists are stored on a different worksheet, the Named Ranges are created fine, as are the ranges that are having the validation applied. The Syntax I am having a problem with is

Public Sub assignDVList(WSD As Worksheet, sListName As String)
Dim DVListName As String
DVListName = "DV" & sListName
Application.Goto Reference:=sListName
With Selection.Validation
.Delete
.Add Type:=xlValidateList, AlertStyle:=xlValidAlertStop, Operator:= _
xlBetween, Formula1:="=" & DVListName

It is the Formula1:="=" & DVListName that is creating the headache. The sub is called as the array moves through the columns, using the header row as the Name for the Named Range, and the data Validation worksheet uses the same naming except it has DV in front.
