read those two pages and if you can’t get it to work after that, come back here…
btw: these two links came directly from the sticky thread at the top of this page, so next time you have a question read the sticky threads first and then read them again, and a third time, and then try a [urlhttp://www.splashdamage.com/forums/search.php]search on the subject you have trouble with. and finally when you did that, read everything again. And after that yopu can make a new thread and ask your question…
Really, it’s all about reading.
