Hi Carinne,
Not sure if this is exactly what you're looking for, but based on your comments maybe try this:
- group the projects by their entry date
- use the dropdown option under this new grouping to group further by month
- add a filter to only pull in 'current' projects (assuming you don't want to count completed projects)
You can then use the summary tab on the report to view a real-time total count of current/open projects to-date.
Kat :)
