You don't have a doubt, you have a question! The difference between "its" and "it's" eludes even most native speakers, but you should have noticed your post is a mess in the preview, read about Markup in the Monastery or at least the "Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!" sentence right under the textbox and fixed the formatting. I doubt people feel like helping someone who posts an unreadable off-topic post. You were too lazy to make it readable, why should we waste our time?
