I have a problem with a question.
My first question is a multiple choice question.
Question A: Do you have any items that were not available at all.
Answer choices:
A B C D E F G H
Question B (also multiple choice): Which of these missing items meet the needs of the population.
If the person chooses: A F, H, let only these choices appear and the person.
Why the second question, the person can choose 3 choices but at the first question but retain only 2 the most important for example at the second.
Does anyone have an idea of how to make the xlsform of the second question
You might be able to achieve your filters using choice_filter
In question b, assuming it shares the same list of options as question A, just put selected(${a}, name) as value of the choice_filter column.
In this case ${a} is the variable with all unavailable items, while name refers to the column name in choices sheet. You can replace a with your variable name.
If you want to limit the number of items that can be selected, then use constraint for either variable like count-selected(.)<=3 if you want not more than three choices
