I have a web site which calculates a discount based on selection of a checkbox, I would like the output into “total” to be rounded to zero (0) decimal places. I have tried a couple of thing and they fail to write to “total”.  
Thank you for the help in advance,

Brian

clear\_form is clearing form of any previous entries  
discountValue is a var dependent on if checkbox is checked or unchecked  
k is var which is the before discount price  
“discount” is input type=“text”  
“total” is input type=“text”  
fillInButton() is a function to send the total to paypal

function discountAmount()  
{  
clear\_form\_elements(document.getElementById(“section\_4”));  
number2 = k \* discountValue;  
document.getElementById(“discount”).value = “$” + “-” + number2;  
p = k - number2  
document.getElementById(“total”).value = “$” + p;  
fillInButton();  
}
