VBA if multiple filter has no results

Hi all,

Please assist me on the below requirement.

> I need to Filter only blanks in Column B, Filter the date after March in Column C and i should exclude all the booked status.

I have the following code wherein it works perfectly but my challenge is sometimes I may not have March month or the booked status during those scenario, only Column B filter has to work but i am getting an error with the below code.

Please refer the attached file and the below code .

Dim rng As Range

    Dim Rw As Long
    Dim sh As Worksheet
      Dim ws As Worksheet
    Dim lastRow As Long, i As Long
    
    Rw = Cells(Rows.Count, 1).End(xlUp).Row
    ActiveSheet.AutoFilterMode = False
    
    Set rng = Range("A1:CC1" & Rw)
    With rng
   
        .AutoFilter
        .AutoFilter Field:=2, Criteria1:="=", Operator:=xlAnd
        .AutoFilter Field:=3, Criteria1:= _
        ">3/31/2020", Operator:=xlAnd
           .AutoFilter Field:=4, Criteria1:="Booked", Operator:=xlAnd
     
        End With

What error on which line of code?
