Welcome back to the community! Randomizing choice order is a feature available within KoBoToolbox to reduce enumerators bias on selecting a response for a question. Choice order can be randomized for any of the select question types. Simply set randomize to true in the parameters column of the XLSForm survey sheet to display the choices in a different order each time the question is displayed as shown in the figure below:
In your survey tab:
In your choices tab:
Alternatively, you could also set randomize in the KoBoToolbox form builder user interface as shown in the figure below:
Please note that a seed value can also be used to recreate the order choices while displaying the choice. For this it will require a number or a reference to another field. This is why you are seeing the error message “seed value must be a number or a reference to another field”. To get rid of this, you could however simply turn off the feature of seed and simply use the randomize to true. It should also work smoothly (if you wish to randomize your choice).
