Well, you didn't lint your code, did you? Which object might "dodcument" be?

But the main point is that you shouldn't try to use document.write() for 
such purposes. Instead, add elements to the document tree in a 
structured manner. If you don't know how to do that, you shouldn't be 
messing around with document modifications before you've read a 
JavaScript tutorial.

Or maybe the main point is really that you are trying to do the wrong 
thing, getting screen size and passing the information to a server. 
Unless you are trying to collect statistics, it's difficult to see what 
useful purpose it might serve (and not so difficult to guess what wrong 
ideas one might try to implement that way).
