Fetcing a SUM would be very helpful

I would love to be able to fetch a sum instead of just seeing it in the view! Using deluge script, I was thinking that if you used the "for each record" to fetch the specific numeric values from a collection/form. Than maybe a built-in numeric function called "SUM ()" to Sum all of those a values to return a specific "SUM" value to a field. This would be very helpful for our business as I use Creator to make invoices and it would save alot of time to not have to manually add or subtract 2 sums to come up with a total amount owed. Thanks so much!! I love the product. Its one of the few services out there that is actually worth every penny.
