Excel 2007 to access 2007

Question

Hello everybody

I try importing data from an excel 2007file to access 2007 using ado and vb6.

the code i m using is :

Sub ADOFromExcelToAccess()
' exports data from the active worksheet to a table in an Access database
' this procedure must be edited before use
Dim cn As ADODB.Connection, rs As ADODB.Recordset, r As Long
    ' connect to the Access database
    Set cn = New ADODB.Connection
    cn.Open "Provider=Microsoft.ACE.OLEDB.12.0; " & _
        "Data Source=C:\VAS_DB_Test.accdb;" 
    ' open a recordset
    Set rs = New ADODB.Recordset
    rs.Open "tbl_Cust", cn, adOpenKeyset, adLockOptimistic, adCmdTable
    ' all records in a table
    r = 2 ' the start row in the worksheet
    Do While Len(Range("A" & r).Formula) > 0
    ' repeat until first empty cell in column A
        With rs
            .AddNew ' create a new record
            ' add values to each field in the record
            .Fields("Numr") = Range("A" & r).Value
            .Fields("Plz") = Range("B" & r).Value
            .Fields("Desig") = Range("C" & r).Value
            .Fields("Norme") = Range("D" & r).Value
           
            ' add more fields if necessary...
            .Update ' stores the new record
        End With
        r = r + 1 ' next row
    Loop
    rs.Close
    Set rs = Nothing
    cn.Close
    Set cn = Nothing
End Sub

the problem i receive a Runtime Error'1004': Method 'range' Of Object'_global'failed  in this line Do While Len(Range("A" & r).Formula) > 0

I was wondering if someone could help me . Other codes will be welcomed (for Access 2007)
