VBA run time error

Question

Hi I am using your code to send an Excel range as an email attachment but get a run time error if I cancel the range. Is there code I can add or a msgbox please to prevent this happening? Thanks code below.

Sub SendRange()
Dim xFile As String
Dim xFormat As Long
Dim Wb As Workbook
Dim Wb2 As Workbook
Dim Ws As Worksheet
Dim FilePath As String
Dim FileName As String
Dim OutlookApp As Object
Dim OutlookMail As Object
Dim WorkRng As Range
xTitleId = "Example"
Set WorkRng = Application.Selection
Set WorkRng = Application.InputBox("Range", xTitleId, WorkRng.Address, Type:=8)
Application.ScreenUpdating = False
Application.DisplayAlerts = False
Set Wb = Application.ActiveWorkbook
Wb.Worksheets.Add
Set Ws = Application.ActiveSheet
WorkRng.Copy Ws.Cells(1, 1)
Ws.Copy
Set Wb2 = Application.ActiveWorkbook
Select Case Wb.FileFormat
Case xlOpenXMLWorkbook:
xFile = ".xlsx"
xFormat = xlOpenXMLWorkbook
Case xlOpenXMLWorkbookMacroEnabled:
If Wb2.HasVBProject Then
xFile = ".xlsm"
xFormat = xlOpenXMLWorkbookMacroEnabled
Else
xFile = ".xlsx"
xFormat = xlOpenXMLWorkbook
End If
Case Excel8:
xFile = ".xls"
xFormat = Excel8
Case xlExcel12:
xFile = ".xlsb"
xFormat = xlExcel12
End Select
FilePath = Environ$("temp") & ""
FileName = Wb.Name & Format(Now, "dd-mmm-yy h-mm-ss")
Set OutlookApp = CreateObject("Outlook.Application")
Set OutlookMail = OutlookApp.CreateItem(0)
Wb2.SaveAs FilePath & FileName & xFile, FileFormat:=xFormat
With OutlookMail
.To = "gtest@email.com"
.CC = ""
.BCC = ""
.Subject = "Tests"
.Body = "Hi . "
.Attachments.Add Wb2.FullName
.Send
End With
Wb2.Close
Kill FilePath & FileName & xFile
Set OutlookMail = Nothing
Set OutlookApp = Nothing
Ws.Delete
Application.DisplayAlerts = True
Application.ScreenUpdating = True
End Sub
