Hi guysI'm a newbie to javascript and have a real problem. I'm using the checkbox calculator script
http://javascript.internet.com/math-...d/calculate.js to use in a seminar registration form. It works fine in IE7, but in FF nothing happens at all. When I look at the error console it gives the error:Line 20: Calc is not defined (line 20 is: if (calc.item1.checked){var witem1 = document.calc.item1.value = item1price;} else {var witem1 = document.calc.item1.value = 0;} I've looked all over the net to find out why FF doesn't like this. Can anyone help? What should it be changed to?Many thanks. James
