function that can change a global var

I need some help, I can't get this to work ->

http://www.all4computers.net/webpages/apply.html

When I try to change Loan Purpose to Finance, it's suppose to change
show to 1, else it's 0.

But Show is always 0. Can someone help me please?

ViperG@gmail.com said:The global variable "show" is changing to 1.
You won't see that in your document.write(), because that only executes as the
page is loading, while show is still 0.
Don't try to debug with document.write(). Use alert(), instead:

function displayr()
{
var main = document.forms['mainform']['Purpose'];
var refine = document.forms['mainform']['Refinance'];

if (main.options[main.selectedIndex].value == "refinance") {
refine.style.display = 'inline';
show=1;
} else {
refine.style.display = 'none';
show=0;
}
alert(show);
}

Ok Thanks, I see.

Well what I'm trying to do is when the user picks refinance, another
form becomes visible, and if not it hides. I have that part figured out
as you can see, but I still have the problem of it displaying some of
the html that goes with that form, I want to hide that also. How would
I go about hiding/showing certain html on the page?
