Filter following an element of a list

[bayemanel]

Hi all
I need help to control a product according to the points of sale.
I want to make each product chosen in a point of sale that the investigator does not have the opportunity to choose this same product in another point of sale

NB: Point of sale: it is in question list format and the products are on a multiple choice question (see photo)

Is this some sort of a price survey?

Oui une enquete de prix @sergiy

@mirela is also working on a price survey, see here:

Protected data preloading - problem

I would like to protect preloaded data in a Numeric question type: [image] When I try to Creating multiple assignments with batch upload, I get this error: 1 error found PL0049 : Variable type cannot be protected. File name: protected__variables.tab Cell: Dec_prec ( Column: variable__name,Row: 1) How can I fix this?

perhaps you could collaborate and through an exchange resolve the problems that each of you are trying to solve.
