There were a couple of syntax errors. Also note that variable names cannot begin with numbers. Neither in PHP nor Javascript. (I changed 1Home to Home1 and 1Away to Away1).

This works for me.

<script type="text/javascript">
function create_req_object()
{
	var req = false;
	
	if (window.XMLHttpRequest)
	{
		req = new XMLHttpRequest();
	}
	else if (window.ActiveXObject)
	{
		var msp = new Array('Microsoft', 'Msxml2');
		
		for (var i in msp)
		{
			try
			{
				req = eval('ne' + 'w Act' + 'iveXObj'+ 'ect(msp[i] + ".XMLH'+ 'TTP");');
			}
			catch(e)
			{
				continue;
			}
		}
	}
	
	return req;
}

function submit_form(form)
{
	var http = create_req_object();
	
	if (!http)
	{
		return true;
	}

	http.open('POST', form.action);
	http.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');
	http.onreadystatechange = function()
	{
		if (http.readyState == 4 && http.status == 200)
		{
			alert("The data has been submitted.");
		}
	}
	http.send('do=addpredict&Home='+ form.Home.value +'&Away='+ form.Away.value +'&eventid='+ form.eventid.value +'&1Home='+ form.Home1.value +'&1Away='+ form.Away1.value);
	return false;
}

</script>
