I'm working on a friends program and I don't see what is wrong with line 8, Char 2 with a message "document.Invest.years" is null or not an object

I have attached the htm file.

Could someone let me know what I'm missing?

Thanks,

Terry

Dave,

Yep there is a <form Name="Invest" align="center">

There is Name="Years" and its a text box that number of years is to be entered.

<title>Tri Star Investing</title>
<script LANGUAGE="JAVASCRIPT">
<!--Hide from old browsers
function calculate(myform) {
var year=document.Invest.Years.value
var year=parseInt(year,10)
if (isNaN(year)) {
alert("Enter the years")
document.Invest.Years.value=" "
document.Invest.Years.focus()
} else {
var rate=document.Invest.IRate.value
var rate=parseInt(rate,10)
if (isNaN(rate)) {
alert("Enter the rate")
document.Invest.IRate.value=" "
document.Invest.IRate.focus()
} else {
var goals=document.Invest.Goal.value
var goals=parseInt(goals,10)
if (isNaN(goals)) {
alert("Enter your goal")
document.Invest.Goal.value=" "
document.Invest.Goal.focus()
} else {

mrate=rate/1200
deposists=year * 12

monthly=goals * mrate/((1 + mrate)^deposists -1)
document.Invest.Monthly.value=Invest

}
}
}
}
