How do I get this to work when calling it from Access?

I'm calling a sql server stored procedure from access and placing the
recordset into excel. I want to total columns "H","I","J" and "K". This
code works in a macro I have in excel but doesn't work when called from
Access.

When i try to compile it , I get a compile error and the word "Sum" is
highlighted in the columntotal sub procedure

xlApp.Workbooks(1).Worksheets(4).Select
ColumnTotal "H"
ColumnTotal "I"
ColumnTotal "J"
ColumnTotal "K"

End Sub

Sub ColumnTotal(ByVal strColumn As String)
Cells(Rows.Count, strColumn).End(xlUp).Offset(2, 0).Value = _
Application.Sum(Columns(strColumn))
End Sub
