CascadingDropDown List 1-dimensional array error

I'm trying to get the CascadingDropDown from the Atlas toolkit to work with a database. I receive this error at the lineReturn values.ToArray().

Error 1 Value of type '1-dimensional array of AtlasControlToolkit.CascadingDropDownNameValue' cannot be converted to 'AtlasControlToolkit.CascadingDropDownNameValue'

Here is the WebMethod.

<WebMethod()> _

PublicFunction GetMakes(ByVal knownCategoryValuesAsString,ByVal categoryAsString)As CascadingDropDownNameValue

Dim makeAdapterAs CarsTableAdapters.MakeTableAdapter =New CarsTableAdapters.MakeTableAdapter()

Dim makesAs Cars.MakeDataTable = makeAdapter.GetMakes()

Dim valuesAs List(Of CascadingDropDownNameValue) =New List(Of CascadingDropDownNameValue)()

ForEach drAs DataRowIn makes

Dim makeAsString =CStr(dr("Make"))

Dim makeIdAsInteger =CInt(dr("MakeID"))

values.Add(New CascadingDropDownNameValue(CStr(dr("Make")), dr("MakeID").ToString()))

Next dr

Return values.ToArray()

EndFunction

Any Ideas?

Replace

PublicFunction GetMakes(ByVal knownCategoryValuesAsString,ByVal categoryAsString)As CascadingDropDownNameValue

With

PublicFunction GetMakes(ByVal knownCategoryValuesAsString,ByVal categoryAsString)As CascadingDropDownNameValue()

CascadingDropDownNameValue() is an array, butCascadingDropDownNameValue is not

Thanks lotusinriver. It works perfectly now.
