Hey guys!!

I'm trying to figure out what I've done wrong here. So I have the
piece of code at the end of this post and I'm trying to reset the text
everytime a button is clicked, but nothing happens. I am using
com.neva from this website:http://www.nevaobject.com/products.htm
(mainly JPrint, but you need Coroutine to make it work)
and it works fine with their sample code at the bottom of this page:
http://www.nevaobject.com/_docs/_jprint/JPrint.htm
So I must have a syntax or scope problem or something somewhere but I
can't figure it out. Can anyone please help me out?

Thanks,

JL
