Yes, I put in the if else.
Originally there was no 'if'. By putting in the 'else' I determined that
this was the point where it failed.
Because it failed here, it seems to indicate that onreadystatechange is not
a valid Firefox construct. Am I wrong ?

I have been looking at the reference, and I will try to use it, but if
onreadystatechange fails in Firefox, I can't see how it will work. Do I just
*not* use it in Firefox?

Am I not doing asynchronous requests?
If not, what did I do wrong?
