Per Customer Dashboard
I have modified the invoicing sample file to work with my business. Essentially Customers are still customers but invoices have been switched to workouts and exercises to products. I would like to make a dashboard so I can relative data to each unique customer. What I would like to be able to see is; count of workouts for each month (current year and prev). Once I can get to this point I can figure everything else out, I just can't get how to do the relationships to make this work right now.
Any help would be greatly appreciated.
