Thanks very much Admin. I am running the code exactly as below with today's date in column 'T' but when filtered column 'T' is not shown

Code:
Sub todaysdels()

 Dim rngFilter   As Range
Dim dDate       As Date

dDate = Date

Set rngFilter = Range("a2:z" & Range("a" & Rows.Count).End(xlUp).Row)

If Application.WorksheetFunction.CountIf(rngFilter.Columns(20), dDate) Then
     rngFilter.AutoFilter field:=20, Criteria1:=dDate
Else
    MsgBox "No delivery for today!", vbOKOnly
End If
    
End Sub
