Below is my code, I have two problems.
1. I would like to remove the E with the box from the webscreen. Is there a way to do this without messing up the calculations?
2. Would like question 2 and the answer to have a , . Example want 100,000 and not 100000.

<html>
<head>
<script type="text/javascript">
function CalculateSum(form)

{
Atext=form.input_A.value;
Btext=form.input_B.value;
Ctext=form.input_C.value;
Dtext=form.input_D.value;
Etext=form.input_E.value;
var A = parseFloat(Atext);
var B = parseFloat(Btext);
var C = parseFloat(Ctext);
var D = parseFloat(Dtext);
var E =parseFloat(Etext);
if(E<300)
form.Answer_for_E.value="Jugs";
else
if((E>=300) && (E<800))
form.Answer_for_E.value="Drums";
else
if((E>=800) && (E<6601))
form.Answer_for_E.value="IBC";
else
form.Answer_for_E.value="Bulk";
form.Answer.value = (A * B / C * D);

}
</script>
</head>
<body>
<form name="Calculator" method="post">

Mcrawford3911,

HTML supports hidden fields, which are invisible to the user but are addressable by javascript and get submitted with the rest of the form.

<input type="hidden" name="input_e" size="10" />

This function returns a string version of a number with commas added to the left of a decimal point (if present). You can pass to it an integer or float or string representations of integer or float. It is tolerant of alhabetic characters accidentally passed.

function addcommas( val ){
	var parts = (''+val).split('.');//Make sure value is a string and split at decimal point (if present) into array.
	var pattern = new RegExp('(-?[0-9]+)([0-9]{3})');
	while(pattern.test(parts[0])) { parts[0] = parts[0].replace(pattern, '$1,$2'); }//Add thousands separators only to the part found left of decimal point, or whole string if no dp present.
	return parts.join('.');//Put decimal parts back together and return.
}

This is a modified version of something I found here, with credit to joshie76.
