Modules & VBA :: Instantiated References In Excel

I'm simply trying to copy a group of cells I've got selected in a separate workbook to the existing sheet.This chunk of code works when I'm testing it in 2 sheets that are in the same file

Code:
Selection.Copy
With Sheets("testdump").Range("B" & y).End(xlToLeft).Offset(, 1)
.PasteSpecial xlPasteFormats, Transpose:=True
.PasteSpecial xlPasteValues, Transpose:=True
End With

I need to make it work while I'm pointing to a different file. This Errors Out

Code:
Dim appXL As Excel.Application
Dim wbk As Excel.Workbook
Set appXL = New Excel.Application
Set wbk = appXL.Workbooks.Open(GrabIt)

[code]...

The application.copy works. I don't know how to structure the 'Pastespecial'. I've used the code to reference other workbooks many times. I'm actually editing in a code that was working for a slightly different application. The sheet I want the information in is open and selected. The sheet it's coming from is open in an instantiated instance.
