Simple next button

1

on my site I have a dyn text field that displays quotes.
1st it loads a random quote and then you can hit ‘next’ to view other quotes.
I have a dyn text field that display what # quote you’re seeing.
when you hit the next button it displays nothing in the quote field but will show the # 1 in the quote # field. you hit next again and it will show you the #1 quote in the quote field and says it’s #2.
here is the AS for the loading of the quotes and the next button:

loadText=new loadVars();
loadText.load(“quotes.txt”);
loadText.onLoad=function() {
rn=random(138);
quotefield.text=this[“quote”+Math.floor(Math.round(rn)+1)];
}
var index=rn;
next.onPress=function(){
quotefield.text=loadText[“quote”+index++];
display.text=index;
}

and here’s the link to the quote movie:

I can’t see what I’m missing that’s making it wrong

thanks in advance
