I need help with this calculate script. In the first function, I cannot seem to assign a value to the global variable grandTotal for whatever reason. I want a span with id grandTotal to display it. If change it to a string it works. So i assigned a the value from the function to it.

How do I either get the global variable to accept it or add the total from the second function calculateChurch() total to it and display an updated total?

<script type="text/javascript">
	var LHtotal;
	var AHtotal;
	var LMtotal;
	var AMtotal;
	var schoolTotal;
	var churchTotal ;
	var grandTotal;
	
	function calculateSchool(orgType) {
		var fund = parseInt(document.getElementById(orgType + 'fund').value);
		var people = parseInt(document.getElementById(orgType + 'people').value);
		var percent = (parseInt(document.getElementById(orgType + 'percent').value))/100;
		var active = people * percent;
		active = parseInt(active);
		var baskets = parseInt(document.getElementById(orgType + 'baskets').value);
		var numPerYear = parseInt(document.getElementById(orgType + 'numPerYear').value);
		var price = 26.00;
		var commision = 0.06;
		var total = fund * active * baskets * numPerYear * price * commision;
		total = total.toFixed(2);
		LHtotal = parseFloat(document.getElementById("LHtotal").innerHTML);
		AHtotal = parseFloat(document.getElementById("AHtotal").innerHTML);
		LMtotal = parseFloat(document.getElementById("LMtotal").innerHTML);
		AMtotal = parseFloat(document.getElementById("AMtotal").innerHTML);
		//alert(LHtotal + " " + AHtotal + " " + LMtotal + " " + AMtotal);
		schoolTotal = (LHtotal + AHtotal + LMtotal + AMtotal);
		//alert(schoolTotal);
		
		if(isNaN(schoolTotal)) {
			schoolTotal = "";
		}
		
		if(isNaN(active)) {
			active = "";
		}
		if(isNaN(total)) {
			total = "";
		}
		var Ototal = parseFloat(document.getElementById("Ototal").innerHTML);
		var Etotal = parseFloat(document.getElementById("Etotal").innerHTML);
		var orgTotal = (Ototal + Etotal);
		var orgTotal = orgTotal.toFixed(2);
		grandTotal = Number(schoolTotal + orgTotal);
		if(isNaN(grandTotal)) {
			grandTotal = "";
		}
		if(isNaN(orgTotal)) {
			orgTotal = "";
		}
		document.getElementById("orgTotal").innerHTML = orgTotal;
		document.getElementById(orgType + 'total').innerHTML = total;
		document.getElementById(orgType + 'active').innerHTML = active;
		document.getElementById("schoolTotal").innerHTML = schoolTotal;
	        document.getElementById("grandTotal").innerHTML = schoolTotal;
