I have a multipage product order form for a theatre website, with plays and workshop as products.
1. I would like to show a free workshop field only if 5 plays are selected. Is it possible with logical condition?
2. I would like also to allow the user to move to the second page (the one with workshop fields) only if 3 plays are selected.
