What i am trying to do is create a list where i can add entries that staff received for Time Off Awards. In my organization time off awards can not go over 80 hours yearly. I have created a list view that groups the awards by staff name and then totals up how many hours they received. Basically the issue i am having is trying to find a way to subtract 80 hours from the total of time of hours in a group. I feel like there should be a easy way to do this. I have sharepoint designer if this is something that needs to be done using that. I am using SharePoint 2010.
