Random room selection

Emanuel Clemente is trying to implement a random selection of a room in the dwelling:

in my survey form I have an air pollution section. In the first part of this section, I have a sensor pre-placement sub-section, whereby I: a) collect a roster of rooms, b) for each listed room, ask to specify the purpose (kitchen, bedroom, livingroom etc), c) randomly select two rooms where to place the sensors. At the end of this randomization, I want to show the labels (e.g. “kitchen”, “bedroom”) -rather than the values (e.g. 1,3,5)- of the randomly selected rooms.

I have written an example for selection of a single room: “PUBLIC QUESTIONNAIRE Random Room Selection”.

Example of selection of two items see here:
