Hey John, most of the time I agree with you... that is, when you're just
summing up values that a user has given you and getting whatever total they
produce, i.e. for a mortgage app where the user enters their financial info
and all you want to know is their total annual income for their application.
The exception is when the user is entering values which must add up to a
given total which is required by some other external mechanism, i.e. in a
grade-weighting schedule for an electronic report-card where grades for
different types of assignments may be weighted differently, but the sum of
all wieghts must add up to 100 ( making each point in the weighting schedule
exactly 1% ). In order to calculate the percentage, you have to know the
total points, so if you want to double-check the teachers to make sure their
math adds up, you can enforce a 100pt total and you know that if their
numbers don't add up to exactly 100 they need to check their math and make
an adjustment.
I _think_ he may be doing something similar to this, although I'm not
certain of that...

JavaScript is case sensitive, so that should be parseInt() rather than
ParseInt().

You might try adding a ParseInt() function around the value as well:
e.g. ParseInt(document.newBillingInfo.SCEPbilledAmount.value) +
ParseInt(document.newBillingInfo.SCEPpenaltyAmount.value)
etc...

IMHO...
In terms of interface design, its easier to auto-calc amounts, then you kind
of take out the human element...
And if youre involving 10 fields for some kind of calculation, and the value
"they" enter is wrong, how do you point to the incorrect amount in the
appropriate field? (assuming youve already set limits, and checked to make
sure the values, if numeric, are within that range).
Its simpler to auto calc it for them. Although, you should also recheck the
math on the server by re-calculating the field amounts again, just to be
sure. )
hope any of this helps,

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;
}

Use the function eval() with each textbox value:
Eval(document.newBillingInfo.SCEPbilledAmount.value)
