excel - Row count on the Filtered data

Question

I'm using the below code to get the count of the filtered data rows in VBA, but while getting the count, it's giving the run time error showing:

"Object required".

Could some please let me know what change(s) is needed?

Set rnData = .UsedRange

With rnData
    .AutoFilter Field:=327, Criteria1:=Mid(provarr(q), 1, 2)
    .Select
    .AutoFilter Field:=328, Criteria1:=Mid(provarr(q), 3, 7)
    .Select
    .AutoFilter Field:=330, Criteria1:=Mid(provarr(q), 10, 2)
    .Select
    .AutoFilter Field:=331, Criteria1:=Mid(provarr(q), 12, 2)
    .Select

     Rowz = .AutoFilter.Range.SpecialCells(xlCellTypeVisible).Rows.count

     ....
End With

If you try to count the number of rows in the already autofiltered range like this:

Rowz = rnData.SpecialCells(xlCellTypeVisible).Rows.Count

It will only count the number of rows in the first contiguous visible area of the autofiltered range. E.g. if the autofilter range is rows 1 through 10 and rows 3, 5, 6, 7, and 9 are filtered, four rows are visible (rows 2, 4, 8, and 10), but it would return 2 because the first contiguous visible range is rows 1 (the header row) and 2.

A more accurate alternative is this (assuming that ws contains the worksheet with the filtered data):

Rowz = ws.AutoFilter.Range.Columns(1).SpecialCells(xlCellTypeVisible).Cells.Count - 1

We have to subtract 1 to remove the header row. We need to include the header row in our counted range because SpecialCells will throw an error if no cells are found, which we want to avoid.

The Cells property will give you an accurate count even if the Range has multiple Areas, unlike the Rows property. So we just take the first column of the autofilter range and count the number of visible cells.
