Just to cover my bets, I would end the if-test chain with

         else return;

so you don't try to manipulate the four page elements if the browser can't 
find them.  That sounds like what's happening, based on the error you're 
getting, although I'm not sure why.  That's all my bleary eyes can see as a 
problem tonight.
