Product Calc connecting to cart

[neelix71]

Hi Guys,

 

Does anybody have any ideas on how I could finish this code?

 

Its a calc that I have added to the "productconfig.tpl" works well and does the calc that I'm after, but I've run in to a problem.

What I'm after is when a client chooses the Main product they can also choose an addon product that they can pay off weekly, the weekly amount has been calculated by the due amount / weeks until due due a.k.a why I made the calc.

Similar to a "product addon" in WHMCS but can be a random amount, but I would like it to show in the cart the same as an addon would.

 

Appreciate any of your thoughts and tricks, Thanks in advance.

<script>

function computeAmount(){

var amount = document.getElementById('amount').value;

var weeks = document.getElementById('weeks').value;

var payment = (amount / weeks).toFixed(2);

payment = payment.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ",");

document.getElementById('payment').innerHTML = "Weekly Amount = $"+payment;

}

</script>

<p>Amount Due: $<input id="amount" type="number" min="1" max="1000000" onchange="computeAmount()"></p>

<p>Weeks Until Due Date: <input id="weeks" type="number" min="1" max="52" value="1" step="1" onchange="computeAmount()"></p>

<h2 id="payment"></h2>
