Is there anything wrong with this code?

Private Sub CopyData()
Dim vArr As Variant, RR As Range
Dim SrcRng As Range, DestRng As Range
Dim Kiln As String
Dim X As Integer, Response As Variant, Style As Variant

' Get Header data
Set SrcRng = Worksheets("DataIn").Range("A3").CurrentRegion
vArr = SrcRng.Value
Worksheets("Report Log").Select
Set DestRng = Range("Source")
Set RR = Range("Source").Offset(DestRng.Rows.Count,
0).Resize(SrcRng.Rows.Count, 19)
RR.Value = vArr
<snip

End Sub


On one particular occasion I had 37 rows of data to copy, and only 34
were copied (plus the error generated below). I've tried this code
numerous times with similar results.

Run-time error '1004'
Application-defined or object-defined error.
