"Hold it up to the screen", by the way, means that we can't tell what's wrong with your code if you don't show us what you've got right now. When you are having trouble with code, post your code.
@vishal_panchal91163: you're over helpingagain. rattonwing21 posted the same thing, word-for-word, one post above yours, which makes me suspect you copied the post for some reason. Unless you have something to add, there's no need to post. Keep the signal-to-noise ratio high.
