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.
