Hiding select multiple options based on selection

[VH_MapS]

Hello,

I have the select multiple question below:


I would like all of the other choices to disappear if the first option (No Equipment Present) is selected. 

I've tried a few different statements in the 'relevant' column (each select one choice generates a repeat) but I'm not having any luck.

Example Statement: if(selected(${Item_Type}, 'Capacitor') and not(selected{${Item_Type}, "NoEquipment")

Can someone point me in the right direction here?

Hey @VH_MapS 

You have many options:

1- Create separate Select_One  question for the equipment availability:

Q\ Equipment Availability:

- Equipment Present
- No Equipment Present

Then use the relevant to hide or appear the next question about the equipment typ.

2- you can use constraint to prevent user from selecting other choices if he selected "No Equipment Present" in same choice list:

if((selected(.,'cpacitor') or selected(.,'regulator') or selected(.,'transformer') or selected(.,'switch') or selected(.,'recloser') or selected(.,'fuse') or selected(.,'meter')or selected(.,'light')or selected(.,'underground_equipment')),not(selected(.,'NoEquipment')),selected(.,'NoEquipment'))

Thank You for the quick reply!

I used the second suggestion. The constraint worked out great!
