I noticed a couple of things that you should sort out:

1) Don't use a capital letter in document.write() 2) According to this: http://www.w3schools.com/js/js_reserved.asp you must not use top as a name for your variables, try something like topMargin. 3) make sure you substitute the variable name everywhere where you have used it 4) you want to make sure you check your message var, you miss a few spaces here and there.

As far as I understood JavaScript doesn't care about spaces inside of the declaration.
