VBA cannot AutoFilter a Range for a certain criteria - excel

Question

I am trying to make a Range object of all entrys and than apply a filter, which searches for a number in there.
I want the Range to hold only the matching entrys afterwards, but I always get the error 1004...
Here the code:
Dim rSearch As Range
Dim rResult As Range
Set rSearch = wbMe.Sheets(iCurSheet).Range("F2:F1000")
rSearch.AutoFilter Field:=iColKey, Criteria1:="=" & wbMe.Sheets(iCurSheet).Cells(iLine, iColKey).Value
The last line throws the exception. I found out that the AutoFilter has to be applied to the first line, so .Range("A1:K1"), but I still don't get why I am not able to Filter on a Range, maybe i get the Object wrong?
Thanks in advance!
Edit:
So I tried some stuff:
Set rSearch = wbMe.Sheets(iCurSheet).Range("A2:K1000")
rSearch.AutoFilter Field:=11, Criteria1:="=" & wbMe.Sheets(iCurSheet).Cells(iLine, iColKey).Value
MsgBox "Count Rows rSearch:" & rSearch.Rows.Count
I expected the MsgBox to say smth less, but I get 999, so it hasn't filtered anything.
My guess that I was filtering the wrong column, but I wanna filter on Col K (I need Col F afterwards to search once more, sry for mixing stuff up).
Now I don't get the AutoFilter exception anymore. But for some reason my rSearch range does not shrink.
How do I shrink my Range?

Count Visible Data Cells (Criteria Cells)
A quick fix could be something like
MsgBox "Count Rows rSearch:" & rSearch.Columns(11).SpecialCells(xlCellTypeVisible).Cells.Count - 1
Note that the headers need to be included in the range for AutoFilter to work correctly.
Using SpecialCells
Sub CountVisibleDataCells()
' Define constants.
Const CriteriaIndex As Long = 11
' Reference the workbook ('wb').
Dim wb As Workbook: Set wb = ThisWorkbook ' workbook containing this code
' Reference the worksheet ('ws').
Dim ws As Worksheet: Set ws = wb.Worksheets("Sheet1")
' Turn off AutoFilter.
If ws.AutoFilterMode Then ws.AutoFilterMode = False
' Reference the range ('rg').
Dim rg As Range: Set rg = ws.Range("A1:K21")
' Store the criteria value from the cell, converted to a string ('CStr'),
' in a string variable ('Criteria'). AutoFilter 'prefers' this.
Dim Criteria As String: Criteria = CStr(ws.Range("M1").Value)
' Filter the range.
rg.AutoFilter Field:=CriteriaIndex, Criteria1:=Criteria
' Reference the visible cells in the criteria column ('vrg').
Dim vrg As Range
Set vrg = rg.Columns(CriteriaIndex).SpecialCells(xlCellTypeVisible)
' Turn off the worksheet auto filter.
ws.AutoFilterMode = False
' Store the number of visible cells of the criteria column
' in a long variable (subtract 1 to not count the header).
Dim CriteriaCount As Long: CriteriaCount = vrg.Cells.Count - 1
' Inform.
MsgBox "Count of '" & Criteria & "': " & CriteriaCount
End Sub
Using Application Count
Sub CountCriteriaCells()
' Define constants.
Const CriteriaIndex As Long = 11
' Reference the workbook ('wb').
Dim wb As Workbook: Set wb = ThisWorkbook ' workbook containing this code
' Reference the worksheet ('ws').
Dim ws As Worksheet: Set ws = wb.Worksheets("Sheet1")
' Turn off AutoFilter.
If ws.AutoFilterMode Then ws.AutoFilterMode = False
' Reference the range ('rg').
Dim rg As Range: Set rg = ws.Range("A1:K21")
' Store the criteria value from the cell, converted to a string ('CStr'),
' in a string variable ('Criteria').
Dim Criteria As String: Criteria = CStr(ws.Range("M1").Value)
' You may need to modify this because 'CountIf' works differently.
' Reference the criteria data range ('cdrg') (no headers).
Dim cdrg As Range
With rg.Columns(CriteriaIndex)
Set cdrg = .Resize(.Rows.Count - 1).Offset(1)
End With
' Store the number of cells containing the criteria ('CriteriaCount')
' in a long variable.
Dim CriteriaCount As Long
CriteriaCount = Application.CountIf(cdrg, Criteria)
' Inform.
MsgBox "Count of '" & Criteria & "': " & CriteriaCount
End Sub
