excel macro error

hi all

i have an example work book attached, there is a macro on both sheet 1 an 2
the macro in sheet 1 will compare column A of sheet 1 and 2 and return what is unique to sheet1 in sheet3
and vice versa for sheet2

the macro (i did not write) works fine for sheet 1, but fails on sheet2 with type mismatch - and i think this is because sheet 2 has 1 less row

can anyone tell me how i could get around this?
----sheet1 macro---------
Sub CopyUniques_old()
   Dim lngLastRow As Long
   Dim varData
   With Sheets("Sheet1")
      lngLastRow = .Cells(.Rows.Count, "A").End(xlUp).Row
      varData = .Evaluate("INDEX(IF(ISNA(MATCH(A2:A" & lngLastRow & ",Sheet2!A:A,0)),A2:A" & lngLastRow & ",""Matched""),0,0)")
      varData = Filter(Application.Transpose(varData), "Matched", False)
      varData = Application.Transpose(varData)
   End With
   With Sheets("Sheet3")
      .Range("A:A").ClearContents
      .Range("A1").Value = "Stock Codes not on new Forecast "
      .Range("A2").Resize(UBound(varData, 1), 1).Value2 = varData
   End With


End Sub


-----sheet 2 macro----------

Sub CopyUniques_new()
   Dim lngLastRow As Long
   Dim varData
   With Sheets("Sheet2")
      lngLastRow = .Cells(.Rows.Count, "A").End(xlUp).Row
      varData = .Evaluate("INDEX(IF(ISNA(MATCH(A2:A" & lngLastRow & ",Sheet1!A:A,0)),A2:A" & lngLastRow & ",""Matched""),0,0)")
      varData = Filter(Application.Transpose(varData), "Matched", False)
      varData = Application.Transpose(varData)
   End With
   With Sheets("Sheet4")
      .Range("A:A").ClearContents
      .Range("A1").Value = "Stock Codes not on new Forecast "
      .Range("A2").Resize(UBound(varData, 1), 1).Value2 = varData
   End With


End Sub
