**Brady**Hey there, I'm trying to come up with a way to include an equation that would add a 25% increase to my order forms grand total if the sub total is greater than $90.

So far this is the code I came up with :(but its not working)

/**

* Calculates the payment total with quantites

* @param {Object} prices

*/

countTotal: function(prices){

var total = 0;

$H(prices).each(function(pair){

total = parseFloat(total);

var price = parseFloat(pair.value.price);

if ($(pair.key).checked) {

if ($(pair.value.quantityField)) {

price = price * parseInt($(pair.value.quantityField).getSelected().text, 10);

}

total += price;

}

});

if (total === 0) {

total = "0.00";

}

else if (total > 90){

total += (total * .25);

}

if ($("payment_total")) {

$("payment_total").update(parseFloat(total).toFixed(2));

}

},

/**

* Sets the events for dynamic total calculation

* @param {Object} prices

*/

totalCounter: function(prices){

$H(prices).each(function(pair){

$(pair.key).observe('click', function(){

JotForm.countTotal(prices);

});

if ($(pair.value.quantityField)) {

$(pair.value.quantityField).observe('change', function(){

$(pair.key).checked = true;

JotForm.countTotal(prices);

});

}

});

**mliz**Hi Brady,

As much as we want to help you the custom script which you are trying to

implement involves advanced knowledge on scripting.

For now what I can suggest is for you to download the full source code of the

form so that you have an idea on what are the variables used for the fields.

You may also want to post it on several scripting forums on the internet and

hopefully someone can be able to post a helpful insight on your code.

Thanks for using JotForm.Regards,

Mliz
