I use confiforms to organise meeting agendas. Therefore I have defined a form "TOPs" where all topics are defined. One of the field in that form is a smart dropdown field to pick a Date from a second form "Meetings" (field "Date" giving the date and the start time of the meeting in hh:mm). The topics are numbered through (1,2,3...) for each meeting in a field "Nr". There is also a field called "Start" and another one called "end" (both time fields hh:mm). The field "duration" gives the needed time for each topic.
Now my question:
Is there a way to calculate the start and end times for each topic in the same meeting? Thereby the first topic (Nr=1) would start with the meeting start time and end with that start time + Duration. The second topic would start with that end time of topic 1 and so forth.
