Using eval { $book->Worksheets($sheet_name) }, I want eval catch the error if the sheet doesn't exist. But the method doesn't work. when the sheet doesn't exist,the perl showes the following error:

Win32::OLE(0.1701) error 0x8002000b: "" in METHOD/PROPERTYGET "Worksheets" at create_rota.pl line 48

I'll appreciate your help.
