Hey lads.



i need to create a investment form that allows the user to enter;
- a cash deposit ( e.g. $5)
- an annual interest rate (e.g. 10%)
- a target savings amount (e.g. $20)

This is my code so far.. where am i going wrong?

CODE
<script type="text/javascript">

function calc() {



var principal = 5;
var months = 0;
var intRate = .12
var factor = 1 + intRate/12;
var amount = principal;
var target = 20;

while (amount <= target) {
amount = amount * factor;
months ++;
}

document.iform.m.value= amount.toFixed(2);
alert ("At " + intRate*100 + "% compound $"+ principal + " will compound to $" + amount + " after " + months + " months" );




</script>
