What is the problem? Please be detailed.
How can i hide an element question when it is not chosen but the question is dependent on the number of family members given.
If use ${number_family_members}>=1, the element appears even if it is not chose. If i used ${family_member_educationneeds} = ‘Enrolment to TESDA/VocTech’ or selected(${family_member_educationneeds}, 'Enrolment to ALS/Elem/HS/SHS'), the elements do not show even they were chosen.
selected(${family_member_educationneeds}, 'Enrolment to ALS/Elem/HS/SHS') is the right idea but it looks like 'Enrolment to ALS/Elem/HS/SHS' is the label of the choice. When you use selected, you need to use the name from the choices sheet. Depending on your choice name, it will look something like selected(${family_member_educationneeds}, 'als_elem_hs_shs').
Because you are using a select multiple, using = will only identify the case where only the als/elem/HS/SHS option is selected so do be sure to use selected.
