Are you just getting a blank white page when you try to view it? In that case look for your php error log (your host may be able to tell you how to view it) and see what errors are coming up after trying to view the blank page.

Thank you for the answer. I sent you also the links for if you want to take a look.

Also i have another question of the use in the templates. For example, in the code that i put, in the old one appears like this:

<vb:if condition="$stocktable != null">

That is right for the templates?

I solve the problem of the hangman. It seems like the PHP_SELF doesn't work in v4. Thanks to Lynne for the help.

But i am working in the other one. My previous question to BirdOprey5 is about it.

Lynne suspect that perhaps the problem is about javascript/ajax. ?Is different to v3 to v4?

This is the code, if somebody knows that it is right or wrong:

//-----------------------------------------------------------------------------
// $Workfile: vbulletin_ajax_stocktrader.js $ $Revision: 1.4 $ $Author: addy $ 
// $Date: 2007/01/02 03:31:59 $
//-----------------------------------------------------------------------------

var stock_xml;

function handle_stock_lookup(symbol)
{
	stock_xml = new vB_AJAX_Handler(true);
	stock_xml.onreadystatechange(handle_stock_lookup_response);
	stock_xml.send('vbtrade.php?do=lookup&symbol=' + symbol);
	
	return false;
}

function handle_stock_lookup_response()
{
	if (stock_xml.handler.readyState == 4 && stock_xml.handler.status == 200)
	{
		if (stock_xml.handler.responseXML)
		{
			var response = stock_xml.fetch_data(fetch_tags(stock_xml.handler.responseXML, 'tag1')[0]);
			if (response != null)
			{	
				var lookup_table = null;
				
				if (document.getElementById)
					lookup_table = document.getElementById('lookup_table');

				if (lookup_table)
					lookup_table.innerHTML = response;
			}
		}
	}
}

Thanks if anybody can take a look to it and verify that it is right.
