Interactive action plan: choose any five tasks
I'm trying to create an interactive action plan in which learners can select any five tasks from a list. These actions then populate an action plan that appears on the next slide when learners click a button.
My problem is finding a way to prevent learners from proceeding to the next slide if they haven't chosen five tasks from the list. I tried to control this by using number variables that increase each time a task is clicked on and then adding a layer that appears if they try to proceed if the number variable doesn't equal 5. However, this doesn't work if learners select and then deselect one of the options: the variable remains changed but the task isn't selected.
Can anyone suggest a way to achieve what I'd like?
