=====  More Tax-inclusive prices, perhaps a better solution.   =====

Put this in the checkout template (right before the closing head tag </head>).

<code javascript>
<script type="text/javascript">
function displayCustomTaxes() {
var order_total = jQuery("#order_total").val(); //takes the order_total amount (this is now a "string") and puts it in a variable
var order_total = order_total.replace(',','.'); //this will replace the "," into "." (this makes the decimals also into the calculation) (example 212,50 into 212.50)
var order_total = parseFloat(order_total); //this will take the amount which is a "string", and make it into an "integer" (text into number)
var tax = FC.formatter.currency(order_total - (order_total/1.25)); //in Norway our tax is 25%, so this will make the 25% tax calculation
jQuery("#tax").val(tax); //this will put the new value into the tax area.
}
jQuery(document).ready(function () {
displayCustomTaxes(); //optional ! this will display the new tax amount BEFORE customers enters in any personal information.
FC.checkout.overload("updatePriceDisplay", null, "displayCustomTaxes"); //this will display the new tax amount AFTER customers enters in any personal information
});
</script>

</code>



Optional! If you also want this in the receipt right after checkout.
Put this in the receipt template (right before the closing head tag </head>).

<code javascript>
<script type="text/javascript">
$("document").ready(function () {

var order_total = $("li.fc_order_total > span.fc_text").html(); //this puts the order_total text-string into an variable
var order_total = order_total.replace('kr',''); //this removes the currency format from the string. (Norway uses "kr", but america uses "$". Change "kr" into your countrys currency.)
var order_total = order_total.replace(' ',''); //this removes the whitespace in amounts over thousand (12 345,67 into 12345,67)
var order_total = order_total.replace(',','.'); //this replaces the "," into "." (for the calculation with decimals) (12345,67 into 12345.67)
var order_total = parseFloat(order_total); //this will take the amount which is a "string", and make it into an "integer" (text into number)

var tax = order_total - (order_total/1.25); //in Norway our tax is 25%, so this will make the 25% tax calculation
var tax = tax.toFixed(2); //this rounds the decimals (up or down) into only two numbers
var tax = tax + ''; //this makes the amount back to a "string", so that we can change the "." back to ","
var tax = tax.replace('.',','); //changes the "." back to ","
$("li.fc_order_tax > span.fc_text").html('kr' + tax); //this puts the new value of tax into the dokument. (Change "kr" into your countrys currency.)

});
</script>
</code>

<wrap hi>This will not change the display of tax on the "email receipt"!</wrap>
