RE: OT javascript addition

[Tim Do]

Hi Brook,
this is what I'm using but getting "expecting )" error... please help =)

function validate()
{
        var sumValue =
eval(document.newBillingInfo.SCEPbilledAmount.value.valueOf()) +
eval(document newBillingInfo.SCEPpenaltyAmount.value.valueOf()) +
eval(document newBillingInfo.SCEPdelinquentAmount.value.valueOf())

        var total =  eval("document.newBillingInfo.SCEPtotalAmount.value")
        if (sumValue != total)
        {
        alert(sumValue)
        document.newBillingInfo.SCEPbilledAmount.focus()
        return false;
        }       
        
        return true;
        
}

I had the same problem the other day. This works FOR SURE:

eval(document.newBillingInfo.SCEPbilledAmount.value.valueOf())+eval(document

newBillingInfo.SCEPpenaltyAmount.value.valueOf())

Using the valueOf() function converts a string to a number.
