I couldn't see those responses but got to them via your links so thank you. I still can't get it to work but I now I think I know why but am unsure how to fix it so I'll post what I hope will be the last question on the subject.
Well could you perhaps be more specific about what is going wrong? I notice you've not replied to either moritz or andreas1234567 in the previous thread.
"can't get it to work" isn't really helpful considering we don't know exactly what you have tried and what error/output you are experiencing? How do I post a question effectively? is worth reading for advice on posting.
If you post your example code, errors/output (perhaps along with your thoughts as to why it isn't working?) someone may be able to point you in the right direction.
