    I am trying to find a function that will allow me to take an equation, and post the output in another location. For example.

    x * y + z = output

    I need to get the output to display in a certain section of the website. Anybody know a java script function that will do what I need???

    Yes you can.
    Create an div element in the location of output(say, name="myDiv").
    On clicking a "get equation result" button call the following function.
    Hope i have answered your question.
    If not, do reply.

    Hi
    Please try my script:
    <html>
<head>
<title></title>
<script language="JavaScript">
<!--

function add()
{
    var num1, num2, num3, total;
    num1 = parseInt(document.calcForm.num1.value);
    num2 = parseInt(document.calcForm.num2.value);
    num3 = parseInt(document.calcForm.num3.value);

	var sum = (num1*num2)+num3;
  
    document.calcForm.output.value = sum;
}
  
</script>
</head>

<body>
<form name="calcForm">
<p>Enter the X Factor:
<br /><input type="text" name="num1" size="5" align="center"></p>
