This happens when the code in my thisworkbook (alerts the expired dates, see code below)

Private Sub Workbook_Open()usfrmlogin.show




Dim LRow As Long
Dim LResponse As String
Dim lname As String
Dim LFname As String
Dim LDiff As Long
Dim LDays As Long








LRow = 2
LDays = 90




With Sheets("DataBase")
  While LRow < 200
 
     If IsDate(.Range("Q" & LRow)) Then
       LDiff = .Range("Q" & LRow).Value2 - Date
        If (LDiff > 0) And (LDiff <= LDays) Then
        
           lname = .Range("B" & LRow).value
           LFname = .Range("C" & LRow).value
           LResponse = LResponse & lname & "," & LFname & "License will expire in " & LDiff & "days." & Chr(10)
         
         End If
       End If
       
       LRow = LRow + 1
       




Wend
  If CBool(Len(LResponse)) Then
    MsgBox "These Licenses are nearing expiration:" & Chr(10) & LResponse, vbCritical, "WARNING"
  
  
  
    End If
   End With
   




End Sub

runs upon login and it displays a reference dialogue box after clicking ok. Then the word date is highlighted. I don't know if i should click/tick one of the choices and i don't know which one to tick. Does my friend need to install a missing library? Thank you in advance
