persistant total

I’ve got a simple site that is only going to be live for 3 months. I need a single form that every user can access that will have maybe 6 line items that will accept user input in the form of a number. I then need to keep a running total for each line item, so there will be 6 calculation fields. I need these 6 calculation fields to be persistent and the 6 line item fields where users enter numbers to not be persistent. So, for example, every time a user accesses the form, the 6 line items are 0. Then, user1 enters 3 for line item1, 5 for line item3, & 2 for line item4. The calculation fields would be 3 for item1, 5 for item3, & 2 for item4. User2 accesses the form and (all line item fields are 0) enters 5 for line item1, 5 for line item2, & 3 for line item4. The calculation fields would now be 8 for item1, 5 for item2, & 5 for item4….and so on.

Is this possible with this plugin? Again, very simple, short-lived site, I don’t need any bells and whistles. I’ve just started playing around with Calculated Fields and so far I like what I see. If the above can be done, I’d very much appreciate any quick tips. Thanks
