<!-- THREE STEPS TO INSTALL RADIO TOTALS:
1. Copy the coding into the HEAD of your HTML document
2. Add the onLoad event handler into the BODY tag
3. Put the last coding into the BODY of your HTML document -->

//Define function to manipulate the form total per item selected/deselected:
function CheckChoice(whichbox) {
with (whichbox.form) {
//Handle differently, depending on type of input box.
if (whichbox.type == "radio") {
//First, back out the prior radio selection's price from the total:
hiddentotal.value = eval(hiddentotal.value) - eval(hiddenpriorradio.value);
//Then, save the current radio selection's price:
hiddenpriorradio.value = eval(whichbox.price);
//Now, apply the current radio selection's price to the total:
hiddentotal.value = eval(hiddentotal.value) + eval(whichbox.price);
}
else {
//If box was checked, accumulate the checkbox value as the form total,
//Otherwise, reduce the form total by the checkbox value:
if (whichbox.checked == false) {
hiddentotal.value = eval(hiddentotal.value) - eval(whichbox.value);
}
else {
hiddentotal.value = eval(hiddentotal.value) + eval(whichbox.value);
}
}
//Ensure the total never goes negative (some browsers allow radiobutton to be deselected):
if (hiddentotal.value < 0) {
InitForm();
}
//Now, return with formatted total:
return(formatCurrency(hiddentotal.value));
}
}
