Hi Peter,
Perhaps the attached demo will give you some ideas. There are three databases which have slightly different facilities, Demo 1 is the earliest and the enclosed User Manual refers to this version. Demos 2 and 3 have additional features which are not mentioned in the User Manual but I am sure you can figure out what they do, if you need any further information then just let me know.
To see some examples of projects, just change the date field at the top of the form to October 2015 for Demo 1 and 2018 for the other two.
Good luck with your project,
Peter Hibbs.
