Hide a group if not relevant

[SueBoelk]

Here is a seed survey that I've asked about recently. 

Having asked questions about related tables concerning this same survey, the suggestions were to use relevant/hidden. (I need help with creating relevant expressions as I am still learning how).

Knowing I will need to add yes/no questions to make the following work: I need to have the relevant/hidden work previous to seeing those sections.

When looking at the form:

If Part II is true, Parts III and IV are not relevant/hidden.  (Farm/Non-Farm Use)

If Part III is true, Part II and IV are not relevant/hidden.  (AG/Grass Seed/Germination)

If Part IV is true, Parts II and III are not relevant/hidden. (Veg Seed Only)

Any help is appreciated. Thank you for your patience.

Relevant is just "true" or "false" in the end. Anything that gets that will do what you want.

E.g., Using your dropdown ${assoc_008}:

selected(${assoc_008},'y')

This would show "Part II" if you selected "Yes", and hide it if you selected "No". You can put as complicated a formula in the "Relevant" column as you'd like.  E.g.,

The real question here is what question do you want to dictate the relevant status?
