[Javascript] js error in IE

[Bob Schwartz]

I am getting an error in IE in a js that seems to be working just  
fine in all other browsers.

MS script debugger says the error is here:

p.innerHTML = (quote[ry]);

in this script


window.onload = function() {
   random_content();
}

function random_content(){
var quote=new Array()
quote[1]='In Instanbul I met a man who said he knew beyond a doubt  
that God was a cat. I asked why he was so sure, and the man said,  
&quot;When I pray to him, he ignores <span class=lastword>me&quot;.</ 
span><br><cite class=right>Lowell Thomas</cite></p>'
quote[2]='Of all God&#8216;s creatures there is only one that cannot  
be made the slave of the lash. That one is the cat. If man could be  
crossed with a cat it would improve man, but it would deteriorate the

harm to ask for what you <span class=lastword>want.</span><br><cite

var ry=Math.floor(Math.random()*quote.length)
if (ry==0)
ry=1;
var p = document.createElement("p");
p.innerHTML = (quote[ry]);
document.getElementById("quotes").appendChild(p);
}


The test page is at:

to see a version with only the problem js active:

http://www.fotografics.it/fife/wp/org/quote.html

and

http://www.fotografics.it/fife/wp/org/quote2.html

(different load methods)

Any ideas?
