Fade In Div Almost There HELP

OKay I modified the fade div seen here:
http://www.brainerror.net/scripts_js_blendtrans.php

My version seen here:
http://charity-funding.us/test/test.html

works great, however the hidden div tag (help1) now blocks access to all the text boxes below.

Can someone please look at the code and suggest a way of getting around this!! I am majorly stuck on this one. HELP!!


<SCRIPT LANGUAGE="Javascript">
function opacity(id, opacStart, opacEnd, millisec) {
	//speed for each frame
	var speed = Math.round(millisec / 100);
	var timer = 0;

	//determine the direction for the blending, if start and end are the same nothing happens
	if(opacStart > opacEnd) {
		for(i = opacStart; i >= opacEnd; i--) {
			setTimeout("changeOpac(" + i + ",'" + id + "')",(timer * speed));
			timer++;
		}
	} else if(opacStart < opacEnd) {
		for(i = opacStart; i <= opacEnd; i++)
			{
			setTimeout("changeOpac(" + i + ",'" + id + "')",(timer * speed));
			timer++;
		}
	}
}

//change the opacity for different browsers
function changeOpac(opacity, id) {
	var object = document.getElementById(id).style; 
	object.opacity = (opacity / 100);
	object.MozOpacity = (opacity / 100);
	object.KhtmlOpacity = (opacity / 100);
	object.filter = "alpha(opacity=" + opacity + ")";
}

function shiftOpacity(id, millisec) {
	//if an element is invisible, make it visible, else make it ivisible
	if(document.getElementById(id).style.opacity == 100) {
		opacity(id, 100, 0, millisec);
	} else {
		opacity(id, 0, 100, millisec);
	}
}


</SCRIPT>

CSS


<style type="text/css">
div.opac_xmpl {
	padding: 3px;
	filter: alpha(opacity=0);
	-moz-opacity: 0;
	opacity: 0;
	position: absolute;
	float: right;
	z-index: 1;
	display: compact;
	border: thin solid #3300FF;
}

.hidden {
	visibility: hidden;
	display: none;
}/* CSS Document */
</style>

DIV Code


<div id="help1" class="opac_xmpl" style="width:675px; height:200px;"> awhole bunch of text</div>


//OPEN DIV code
javascript:opacity('help1', 0, 100, 500)

//CLOSE DIV code
javascript:opacity('help1', 100, 0, 500)
