Add Contents Of 2 Text Box's

Right, ok, well I have designed a form that will display a price (22.34) in
a text box, and another price in the other text box... I also have a blank
text box... Now I want to add both the prices together and get a total in
the bloank textbox..

I got this example off a website sumwhere.. But it does not display the
decimal number, it only displays the whole number..


var number1 = parseInt(document.forms[0].CasesSellingPrice.value);
var number2 = parseInt(document.forms[0].AccessoriesSellingPrice.value);
document.forms[0].total.value = number1 + number2;
