Thanks Jeff once again,
I want everyone to see the count and also after they have registered I want to let them be able to change between zones so long as there is space available in the zone they want. So I need to manage increment for the new zone and deduction from previous zone during an edit, which is the part I am struggling the most with.
Do I need something like another field on the Attendee table to capture ‘Previous Zone’ and then some action on the edit screen’s ‘Done’ to compare current Zone with Previous Zone and do some if then else to deduct and increment the zone counts (and also finally set Previous Zone to have the same value as current Zone)?
Or maybe I should be using a screen rather than the default edit?
Sorry for all the questions and many thanks for your patience and answers!
