RE: OT javascript addition

[Matthew R. Small]

Wow, that's correct but it sure does have a lot of parentheses.
Shouldn't the order of precedence be enough to get the addition correct?

sorry
try this:

if ((eval(document.newBillingInfo.SCEPbilledAmount.value)) +
(eval(document.newBillingInfo.SCEPpenaltyAmount.value)) +
(eval(document.newBillingInfo.SCEPdelinquentAmount.value))) !=
document.newBillingInfo.SCEPtotalAmount.value)

Thanks Stephen.. I tried that earlier but that only concatenates it

Tim,
try adding () around the addition part like so:

if ((document.newBillingInfo.SCEPbilledAmount.value +
document.newBillingInfo.SCEPpenaltyAmount.value +
document.newBillingInfo.SCEPdelinquentAmount.value) !=
document.newBillingInfo.SCEPtotalAmount.value)


This should force the addition to take place before the comparison.

PS are you checking for numeric input only

This could be done like so:

if ((isNaN(document.newBillingInfo.SCEPbilledAmount.value)) ||
(isNaN(document.newBillingInfo.SCEPpenaltyAmount.value))  ||
(isNaN(document.newBillingInfo.SCEPdelinquentAmount.value))  ||
(isNaN(document.newBillingInfo.SCEPtotalAmount.value))
        {
        alert("The amounts must be numeric, Please
check the values.")
        document.newBillingInfo.SCEPbilledAmount.focus()
        return false;
        }
else
        {
if ((document.newBillingInfo.SCEPbilledAmount.value +
document.newBillingInfo.SCEPpenaltyAmount.value +
document.newBillingInfo.SCEPdelinquentAmount.value) !=
document.newBillingInfo.SCEPtotalAmount.value)
        {
        alert("The total Billing amount does not add up correctly,
Please check the values.")
        document.newBillingInfo.SCEPbilledAmount.focus()
        return false;
        }

        return true;
        }
}


or something like that ;-)

this is untested code but hopefully will give you something to work
with.

HTH

Stephen

Hello,

Can anybody show me how you would I would validate the sum of several
text boxes?  This is what I'm trying to use but not having luck.. thanks
in advance.

function validate()
{
 if (document.newBillingInfo.SCEPbilledAmount.value +
document.newBillingInfo.SCEPpenaltyAmount.value +
document.newBillingInfo.SCEPdelinquentAmount.value !=
document.newBillingInfo.SCEPtotalAmount.value)
        {
        alert("The total Billing amount does not add up correctly,
Please check the values.")
        document.newBillingInfo.SCEPbilledAmount.focus()
        return false;
        }

        return true;

}
