Paste unformatted text into Word via Excel

I'm new to VBA. I'm trying to take an excel range and paste it as unformatted text into Word. The problem is I can't figure out how to paste as unformatted text specifically. Everything else works fine.

Sub PasteListToWord(SheetName As String, NumLines As Integer)

    Dim WordApp As Object
    Set WordApp = CreateObject("Word.Application")
    WordApp.Visible = True
    Worksheets(SheetName).Range(Cells(1, 1), Cells(NumLines, 1)).Copy
    WordApp.Documents.Add.Content.PasteSpecial DataType:=wdPasteText
    Application.CutCopyMode = False
    Set WordApp = Nothing

End Sub

Running this says "Compile Error: variable not defined." with wdPasteText highlighted. I tried pasting this way in word and it WORKS, but not in excel

All my code works if I replace the paste line with

WordApp.Documents.Add.Content.Paste

But this isn't what I want since it pastes everything as a table.

Any ideas?

Thanks

EDIT: I should probably mention I'm using Office 2010 Beta :o
