Re: Real-time form-field updating

This is code from "http://www.mcfedries.com/JavaScript/AddItUp.asp";
that looks like it does what I am looking for, but it is based off of
drop down menus and I am using text boxes for my entry source. Can
anyone tell me how I need to edit this so that it will work for text
boxes?


<SCRIPT LANGUAGE="JavaScript">
<!--
function AddItUp(form) {
var item, firstValue, secondValue, thirdValue;

// Get the value of the item that's selected in the first list
item = form.first.selectedIndex;
firstValue = eval(form.first.options[item].value)

// Get the value of the item that's selected in the second list
item = form.second.selectedIndex;
secondValue = eval(form.second.options[item].value)

// Get the value of the item that's selected in the third list
item = form.third.selectedIndex;
thirdValue = eval(form.third.options[item].value)

// Add up the value and display the total
form.total.value = firstValue + secondValue + thirdValue
}
//-->
</SCRIPT>
