Counting a group of data as one

How do I go about counting a group of data as 1 item? For example, I have a user who worked on 11 work orders, but only 10 were completed and I am trying to get the # of work orders completed. The problem I am having is it is counting each work day for each completed work order, so for example, if one work order was worked on for 5 days, it counts that work order as five and not one. I need it to ignore the number of work days and just give me the one work order in the count.use distinct count instead.|||I tried that, but it does not work in this case. I am getting closer with it, but now I have a different problem. It seems that the total I need is always off by 1. For example, if a person worked on 7 work orders and 5 of them are closed or completed, it is giving me a count of six. I need to figure out how if a work order has a certain status, to take that total and subtract 1 from it, otherwise leave it alone. Any ideas?|||It would be good if you would post an example of your current report and your desired result.|||You might be able to use a running total with a formula to determine which records to count; reset at the appropriate level.
