I have 2 workbooks open, and I am trying to copy one range of cells from one workbook into the other workbook based on a condition. The program keeps on breaking at the first For Each loop with the 
Subscript out of range
error and I am lost as to why.
I looked at other threads here, and they said that the error comes from not having an Open workbook. I implemented that, and it still gives me this error.
I am new to VBA. Any ideas?
Sub TransferCells()
    Dim aggrange As Range
    Dim AnalyticalCell As Range
    Dim BatchCell As Range
    Dim analyticalwb, batchwb As Excel.Workbook
    Dim SEHPLC, CultureDay As Worksheet
    Set analyticalwb = Workbooks.Open("\\ntucsmafps06.na.jn.com\Hom$\APachall\Ta Big Data\Cas tical Results (4).xlsm")
    Set batchwb = Workbooks.Open("\\nctusmafp0s6.na.jn.com\Hom$\APachall\Ta Big Data\20180420_Fed Batch All Data_0.xlsx")
    For Each AnalyticalCell In analyticalwb.Worksheets("SE-HPLC").Range("A1:A87")
        For Each BatchCell In batchwb.Worksheets("Sheet3").Range("A2:A125271")
            If AnalyticalCell.Value = BatchCell.Value Then
                Set aggrange = Range(ActiveCell.Offset(0, 11), ActiveCell.Offset(0, 13))
                aggrange.Copy (Destination = Application.Workbooks("20180420_Fed Batch All Data_0.xlsx").Worksheets("Sheet3").Range(ActiveCell.Offset(0, 3), ActiveCell.Offset(0, 5)))
            End If
        Next BatchCell
    Next AnalyticalCell
End Sub
