Thank you Hartmut for responding, it is very much appreciated. This doesn't directly work for me here - as I will have an unknown number of entries that need to be summed, and entries added as multiple different records over many months. (whereas you have a defined number of entries - in this case 8 entered into a single record).
However, I do like what you have done, and can certainly use that ideology in other areas of my work.
Thanks again.
