Does Relevant "except" exist with XLS form?

Hello All,

I am finalizing a XLS form and there is a question for with I am facing problems:

The initial question is: For which purpose did you use the filtered water? >> select multiple wateruse (to drink, to cook, to clean, for personal hygiene, other).
Then, the question I would like to ask is "if NOT to drink, why" (the objective is to know if the water was clean enough for drinking, after purification items distributed)

I know how to use Relevant (${XX}="yes" or selected(${XX},'YYY') ). But here the question is not: if you selected XX but it is if you DID NOT selected "to drink". I am sure it exists but I could not find online.

Thanks you all in advance for your help!
