You should at least give a link to a possible thread or solution. This is not just a RTFM or go search site with no help provided to them whatsoever. At least be more prone to give some type of advice or ask for error messages, etc. This has been asked before but its impossible to get everyone to search first before asking.
If your provide maybe a little more details on your issue we might be more of help. Any errors? Why you htink its not working, etc? And of course a search on the site might find your answer before anyone might post it for you, once we get more details.
