Sikboy has a good point... most newbie questions have been answered several times over in this forum. Also the Help file that comes with the Editor is a great source for learning; you just have to make sure you "stick with it" until it makes sense. Many of the things you'll do in the editor are not intuitive or easy, so you have to be patient with yourself.
In the future, name your posts something more meaningful than "need help"... you know, something specifically pertaining to your question, like "need help with loading my custom terrain"... this will help others when doing searches for previously covered topics.
And in the end, there's always somebody in here happy to help you. The TE is lots of fun, but it does have its price. Stick with it, and you'll be making MA maps before long!
and good luck.
